If Eleventh Hour
was still around (the U.S. version), a crossover with Fringe
would have been cool. Dr. Hood and Rachel are investigating what seems to be one of their usual scientific mysteries, perhaps involving some strange human mutation or somesuch, but it turns out it's part of The Pattern, and they're joined by Fringe Division to solve (or not) the bizarre case. Hood & Walter would make an interesting pair.
Rachel: I didn't know we had a "Fringe Division".
Hood: It's classified.
Rachel: Then how do you
know about it?
Hood: I don't.
