Who: Leslie & Lisa Trevor. Possibly Albert or William.
Where: The Tri-Cell restricted lab on the basement level.
When: Sometime after she escaped Leslie's home and her confrontation with Wesker.
Why: They've haven't seen each other in a few days.
After the fight between the two biological weapons, Lisa was compromised and she faltered thanks to William Birkin's sedative and Albert's strength. When she was shoved in was nothing more than a room with nothing in it with the exception of a place to use the bathroom in the back. Since then, she fought with scientists and murdered them until that heavy shackle was replaced on her wrists that kept her from much movement.
The room had bright lighting and a very basement dwelling look to it. It was true, she was given difficult restraints, heavy sedatives and no privacy in a place that seemed much less helpful. At first look, her face and body had some bruising from her fight as well as collar that had an automatic mechanism for sedatives.
A this point, she thought of nothing, sitting there.
