Mooni

Mooni is the sister of Subject C-7692, and snuck into the facility to find out what happened to her (apparently, Mooni thought that Subject C-7692 was at this facility against her will for nefarious reasons, not realizing that this was more or less quarantine).  Sadly, Mooni accidentally let out one of the few captured imposters the facility had, and it attacked her.  While she was rescued, it is clear she has come into contact with the mutagen, but has yet to show any signs of mutation like the other subjects, possibly due to her only getting a lower dose of the mutagen.

Mooni must stay in the facility under quarantine to monitor her condition, and see if the low dose of mutagen has any delayed effects.
