Iris was initially poorly served on the show for the majority of season one, but things picked up with her character quite considerably this season. Keeping her and Barry apart for most of this run was definitely a good move, as she got to stand on her own two feet as a character.
Poor Caitlin. First Ronnie, then Jay. That woman really does have terrible taste in romantic partners. Sadly, that and her connection to evil doppelganger Killer Frost seem to be the only things that define the character, as she is currently the most underused Team Flash member.
What a guy Joe is. No matter what happens – be it time travel or parallel universes or long lost sons – Joe West takes it all on the chin and is continually a great father figure to Barry, Iris and pretty much anyone on Team Flash. We’d all like Joe for a dad.
