The answer is Tessa

"So, did you happen to notice how the young lady tensed up?" Elena inquired, as she returned to the breakfast table where Blake was seated.

Blake shrugged nonchalantly. "I didn't really pay much attention," he replied, taking another bite of his food. "Where's she from, anyway?"

Tessa cleared her throat before responding, "She arrived on the island while you were unconscious, Blake."

Blake furrowed his brow in confusion. "And who exactly is she, then? Why is she here?"

Elena chuckled nervously, interjecting, "Oh, I must have forgotten to mention, there are several lodges scattered about the island."

Elena leaned in, her voice laced with casual charm. "You see, Blake, this island isn't just a holiday destination. It's also a business venture for us. A little slice of paradise that we manage together."
