So, that makes three prisoners in Zoom's dungeon: Barry, Jesse, and the Man in the Iron (?) Mask. What does he want with them all? At this stage, we know that he kidnapped Jesse in order to force Wells into helping him get faster, and that in regards to Barry, he wants to steal his speed. Now he's got Barry, he doesn't really need Jesse, does he? Unless, of course, she is actually already the speedster Jesse Quick, though given there's been no sign of that it seems unlikely. The masked man, meanwhile, is something of a wild card in all of this - is he also a speedster? Someone Zoom uses as a stand-in of sorts, hence the mask? Quite what he has planned for all three of them is intriguing, as he seems set to keep them locked up a while longer, rather than stealing Barry's speed and being done with it. Hopefully we'll get more on that next week, especially since Barry's going to get out of it somehow.
