((Great, now my character is a literal monster bait...Yeah, tough luck. Since you mentioned the "memorizing" part, I'll take it my character has some idea of what may have happened. And are you keeping track of the Makarov's clip? The magazine sizes vary from 8 to 10 and 12 bullets.))
Mortimer reawakens inside the elevator and stands up, recovering the disciplined stance he had learned after so much time practicing military tactics. But he also knew he was probably not the same anymore.
He saw the creatures' eyes, and they had saw him; Mortimer felt as if they had somehow etched his face, scent and signature into their mind, sharing his characteristics between them. He took some time to check where the elevator was going before starting a conversation.
"Um, Basement? Yeah, I could have some of what they hid there. And some more firepower may prove beneficial, unless it has already been all exhausted."
The russkie examines his pistol, still maintaining his stance to prevent any missfires.
"I should also mention I think those creatures got something into me, like a tracking device of sorts. Not the physical one, of course, but you get the idea. Either that or they just got all my info and they'll track me to hell and back."
He stops for a moment.
"I am probably a hazard for the team. What do you think? I can leave you alone if you so wish. To be sincere, I know these monsters are beyond common sense. I may be more resilient to suggestion..."
He fondly remembers the memories of his father teaching him how to cope with pain and distractions under stress and at gunpoint. His lips form a slight smile. Old bastard.
"...But even if they do not break my mind, I'm sure they'll break my body sooner or later even if I follow you, since I'll be their prey. Either that or they leave me mostly unscathed and start to pick off each one of you to finally kill me when I am no longer of use. I may just be going crazy, but that is what I think. Bluntly put, I feel as if they are the hounds, and I have just became the rabbit."
He exchanges the barely used magazine for the fresh one, just in case he has to face an occasion where there will be no time to reload, pulling the slide and chambering another bullet with a sharp metallic sound.
"Well, this rabbit can kick and bite. Hard."
His eyes show steely determination. The youth really means what he just said; if he proves to be more of a problem to the team than he is worth, there is no problem in being left to fend off for himself. After all, there are five more lives on the line.
Exchange barely used magazine for unused one, prepare to shoot at anything dangerous. When the elevator doors' open, be the first out and secure the area before anything else.
