In the movie The Invisible Man (2020), in the treatment center, Cecilia is visited by Adrian's brother, who claims that he can "make all this go away" if Cecilia agrees to have the baby and goes back to Adrian.
Literally, he says
Right now, you're a murderer. But I can change that.
Is there any way that he could actually do that? How would he explain the murder of Cecilia's sister? He can't tell the truth of course, but if he doesn't I don't see how there's even a slim chance that anything could explain how Cecilia is holding the very knife that was used to murder her sister a second earlier, with plenty of witnesses around?
