Barry loses his memories.

Cause and Effect is the most the lighthearted non-crossover episode of the season in a way thats very meta.

However, its an enjoyable one that brings some much-needed levity.

But overall, Barrys amnesia turns this into an incredibly playful hour thats a lot of fun to watch.

Im not the only one who loves this version of Barry.

Iris does, too.

In this case, Joe becomes a surrogate for the writers.

Unfortunately, reality ruins the current illusion.

Killer Frost shows up at S.T.A.R.

Labs because Savitar has lost his memory, too, which makes him useless to her.

So Caitlin agrees to help Team Flash restore Barrys memories.

Yes, Barry is still a hero even with amnesia.

He runs out to the scene of the fire and is overwhelmed by what he sees.

Basically, its portable electroshock therapy, which SOUNDS TOTALLY SAFE, RIGHT?!

But they have no other option since lives are in danger.

Barrys memories come flooding back.

That restores Savitars memories, too, thereby, thankfully, restoring Wallys powers.

So Kid Flash speeds out to the scene of the fire to help Barry put it out.

Yes, the day is saved!

The other thing Ive been complaining about a lot this season is how the show has handled Iris.

Yes, Im so excited for the return of King Shark!
