Alpha Nathan Pov.

I hadn't originally planned to stay at the resort for more than a few days. Just long enough to establish our relationship away from the scrutiny of the Pack and allow Emily time to adjust to her new role without constant observation.

"A week should be sufficient," I had initially thought while making arrangements. "Then we can return and begin integrating her properly into Pack life."

However, Mila's temperament had grown increasingly unpredictable and concerning. This forced me to reconsider our timeline.

"We'll need to stay until she regains her equilibrium," I decided ly. I recognized that abandoning her in this fragile mental state could lead to disastrous consequences for both her personal life and our Pack's reputation.

"The tropical environment might help stabilize her emotions," I reasoned hopefully, though privately harboring significant doubts. "Perhaps the distance from her mate and the change of scenery will provide the perspective she seems to be lacking."

Emily had been surprisingly understanding about extending our trip to accommodate my sister's needs. Her compassion was another unexpected quality that gradually endeared her to me despite our unusual beginning.

"Family should support each other through difficult times," she had commented when I explained the situation. Her simple statement carried unexpected weight given her own complete lack of family support throughout her ordeal.

At this point, I was increasingly convinced that Mila needed serious intervention. Either professional psychological help to address whatever emotional crisis had triggered this personality change, or perhaps a more direct supernatural approach to exorcise whatever darkness had taken root in her psyche.

"Something is fundamentally wrong with her," I confided to Emily as we finished packing our luggage. "This isn't just normal relationship trouble or temporary emotional distress. It's as though something has corrupted her core personality."

Emily listened attentively, her expression thoughtful as she considered my concerns. "Do werewolves have therapists or counselors?" she inquired with practical directness that I found refreshing. "Someone who understands supernatural psychology?"

I nodded, appreciating her pragmatic approach to the situation. "Yes, we have healers specialized in mental and emotional trauma, particularly issues unique to our kind like mate-bond distress or moon-cycle imbalances. I'm considering contacting one of the most respected practitioners once we return if this behavior continues."

What I didn't share with Emily was my more immediate plan. I wanted to observe Mila closely during our trip and determine which intervention might be most appropriate.

"I need to see which approach would be most effective," I thought grimly. "Whether she needs healing or something more direct to drive out whatever has possessed her."

Mila packed her own luggage with remarkable efficiency given her disturbed state. She maintained a permanent room in my castle and consequently had an extensive wardrobe available despite the unplanned nature of this trip.

"I'm ready whenever you are," she announced with uncharacteristic coolness when I checked on her. Her previous emotional volatility was temporarily subdued beneath a mask of indifference that seemed almost more concerning than her earlier outbursts.

"Are we taking the Gulf stream or the larger jet?" The casual question, delivered with studied nonchalance, struck me as oddly calculated. It was as though she were deliberately projecting normalcy to disarm my growing vigilance.

"The Gulfstream," I replied cautiously, studying her for any sign of the inappropriate behavior she had displayed earlier. "More efficient for the distance and landing requirements at our destination."

She nodded with apparent disinterest, turning back to arrange her cosmetics case with meticulous attention. "Will your human be joining us for meals, or will she require separate feeding arrangements?"

The deliberately provocative question revealed the continuing hostility beneath her facade of calm. The subtle emphasis on 'human' was clearly intended to establish hierarchical distance between herself and Emily.

"My Luna," I corrected firmly, emphasizing Emily's proper title. "Will be treated with all the respect her position deserves. I expect you to remember that, Mila."

With all three of us finally prepared, we departed for the airport in my private limousine. The atmosphere inside the vehicle was tense with unspoken conflict and emotional undercurrents.

"How long is the flight?" Emily asked softly, clearly attempting to break the uncomfortable silence that had descended upon us.

"About six hours," I responded with deliberate warmth, reaching to squeeze her hand reassuringly. "The jet has comfortable sleeping accommodations if you'd like to rest during the journey."

Mila snorted softly at this exchange, her expression conveying thinly veiled contempt as she stared pointedly out the window. She was deliberately creating distance between herself and our conversation.

I found myself constantly monitoring the physical space between us, maintaining strategic positioning to ensure Mila remained at an appropriate distance from both Emily and myself. The hypervigilance was exhausting but necessary given her recent behavior. I felt like a soldier in enemy territory, constantly scanning for potential threats or ambushes that might emerge from an unexpected quarter.

"We just need to get through this trip without incident," I reminded myself firmly. "Then we can address whatever is happening with Mila in a more controlled environment."

Once aboard my private jet, Mila immediately and unexpectedly rushed to claim the seat beside mine. Her movement was so deliberate it could only be interpreted as a calculated power play.

"Mila!" I reprimanded sharply, my patience wearing dangerously thin with her continuing provocations. "I need to sit next to my Luna."

The statement was delivered with firm Alpha authority that would have instantly compelled compliance from any normal Pack member. Yet Mila merely settled more comfortably into the seat, flashing a challenging smile that bordered on insubordination.

"I thought family should stick together during flights," she responded with mock innocence. Her tone was deliberately childish as though imitating the little sister she had once been rather than the grown woman she now was.

The regression to childlike behavior was another concerning sign of her deteriorating mental state. Or perhaps it was a deliberate manipulation tactic designed to invoke my protective instincts. Either possibility was troubling in its implications for her psychological wellbeing and our relationship moving forward.

I turned apologetically toward Emily, genuinely regretful that she was being subjected to this dysfunctional family dynamic during what should have been a romantic getaway.

"Sorry baby," I murmured with genuine contrition, silently communicating my frustration through an expressive eye roll directed away from Mila's line of sight. "In less than an hour you'll be free and we'll be alone."

The subtle promise contained in my words seemed to reassure Emily. Once we reached our destination, I would ensure we had private time away from Mila's disruptive presence.

"It's okay, Nathan," she replied with a gentle smile that conveyed understanding far beyond what I deserved given the circumstances. "She's your sister after all. Family is important."

Her simple statement, delivered without resentment despite Mila's obvious hostility toward her, highlighted a generosity of spirit that seemed remarkable given her traumatic background. Rather than becoming defensive or competitive, Emily consistently demonstrated patience and emotional maturity that put my sister's behavior in even starker contrast.

Mila's reaction to this exchange was immediate and disproportionate. There was a visible tightening of her jaw followed by an explosive outburst that shocked even me despite my growing accustomed to her erratic behavior.

"Nathan!" she practically snarled, her voice carrying a possessive edge that sent warning signals through my Alpha instincts. "I'm the only one who is allowed to call him by his name! Got that?"

The territorial claim was so inappropriate and bizarre that it momentarily stunned me into silence. My own sister was attempting to restrict how my mate addressed me. This represented a level of boundary violation that went beyond even her previous concerning behavior.

Recovering quickly, I clenched my fist and raised it near Mila's face in a clear warning gesture. My patience had finally reached its breaking point.

"One more word and I will slap your face," I threatened with deadly seriousness, my voice dropping to the dangerous register that signaled my wolf rising closer to the surface. "Got that?"

The reciprocal use of her own phrasing was deliberate. It was linguistic mirroring designed to emphasize the inappropriate nature of her challenge.

Instead of responding with appropriate contrition or even defensive anger, Mila slumped back in her seat with an exaggerated pout. Her lower lip protruded in a childish expression that might have been amusing in a ten-year-old but appeared deeply disturbing on a thirty-year-old woman.

"You never used to be so mean to me," she muttered petulantly, crossing her arms across her chest in a gesture of theatrical sulking that further highlighted the concerning regression in her behavior. "You always took my side before she came along."

The accusatory glance she shot toward Emily contained such naked hostility that I instinctively shifted my posture to create a protective barrier between them. Emily showed no visible reaction to the aggression directed her way.
