That would make quite a bit of sense, given their current circumstances, and it might get her just the help she needs to get an exit.

You answer determines weather I leave you exposed like this or give you a free arm. Is the slime a part of you, or are you a part of it?" she asks, tensing herself so she can make a quick run for it if something goes wrong. She's not going to be taking any chances with Lex quite yet, though she did have to admit, she was a bit jealous of the changes that seemed to have occurred to the human's body.
