Yeah seriously it felt like they brought Thawn back just to say, hey he's back and definitely going to be a villain to fight in the future in case Barry runs out of people to fight.

Great episode but I just can't help but groan in frustration at Barry screwing around when he should be smart enough not to… I mean common Barry what part of Earth 2, opposite and different do you not understand. The writers are really playing up his naivety.

Last I read it's supposed to be, Barbara being cripple and the events are anyways.
