7) “You Look Really Familiar…”
Fans of the so-called WestAllen relationship were heartbroken when Barry and Iris finally cemented their feelings for each other in season two’s finale – only for Barry to completely undo their life together in order to save his parents. The trailer reveals that not only are the pair no longer a couple, and not as close in general because they didn’t grow up together, but Iris doesn’t even remember Barry.
Presumably in this timeline they haven’t seen each other much since they were friends as kids, or perhaps even that didn’t happen as before. Nevertheless, the trailer also promises that, whatever the timeline, Barry and Iris are meant to be together. Within a minute, the pair are already locking lips again and alt-Iris has deduced that they were closer in the original timeline. You just can’t keep those crazy kids apart.
