I actually liked that they didn't mention Supergirl, I hope they keep that show completely out of the Flash.
Yeah the whole episode was kinda filled with dumb stuff like zooms spidey-sense. Like why didn't Harry just put a shitload of deadly poisons or a paralysis in with barry's speedforce or why Jay didn't have blue lightning if he was Zoom's time travel duplicate?
Oh and why would he say "well this complicates things?" when he killed Jay if that was his plan all along?
