He suggests the only way to help patients is by turning them super with eugenics.

Of course, his peers dont want any part of that and walk out on his lecture.

This opening scene does a good job of setting up how, well, pathetic his life is.

Things are about to get wild.

Asweve revealed already, Deegan tinkers with reality and Oliver and Barry swap lives.

The episode wastes no time in digging into how humorous this entire situation is.

(This episode name-dropped so many things!)

Unfortunately, Team Flash doesnt believe that theyve switched lives and ends up locking them up in the pipeline.

(ASIDE:One of the things I loved about this episodes humor is how self-aware it was.

Labs prison is still pretty problematic.

Thankfully, Kara can see them for who they are and doesnt believe Oliver is Barry and vice-versa.

I also loved how Lois Lane introduced herself as Lois Lane,Daily Planet, which feels very on-brand.

This callback definitely felt earned, especially sinceThe Flashis coming off of its retrospective100th episode.

Alas, Oliver isnt so amused by the comeback and throws a fit.

Have Barry and Oliver ever had an exchange quite like this?

I dont think so, but it feels earned and is a great beat for their relationship.

So, Barry, Oliver, Supergirl, and Superman head back to Earth-1 to save the day.

Amazo, you have failed this city!

With the day saved, its time to return to the matter at hand: fixing reality.

All in all, I really enjoyed the first part of the crossover.

Not only that, but it also took time for important character beats.
