Figure it all out is very abstract to Will Henry. He knows the Witches had done their best to explain it all, but trying to condense the entirety of how and why they're all here and going through this into one lecture was... a Sisyphean effort. It will probably never fully make sense, but the pieces of context will have to come one at a time. He also doesn't have any faith in himself to understand it, that was for someone like Doctor Warthrop. He can imagine it, really, the Doctor's demanding questions with no clear answers and a childish tirade about Must I do everything myself?

"Doctor Warthrop might," there's a mixture of pride and revulsion in this.

He stuck by the man because he really believed in the esteem of his work, but being his assistant was an unpleasant business. Warthrop was quick to forget he was a person, not just a tool at his disposal. So Will Henry tended to forget that too, there at his side.
