Wally, Ray and others in “Unfinished Business”

Wally

Hey, uh, what happens if we don't repair history?

Ray

Working theory: time is frappéd together like a smoothie. So instead of just dealing with Julius Caesar in Aruba, we have to fight off Genghis Khan, a herd of woolly mammoths, and a swarm of locusts from the Old Testament.

Nate

And Mallus is freed from time jail so he can rule over this giant mess.

Wally

So, worse than Flashpoint.

Ray

Uh, is that what we're calling the thing that Barry did? Oh, I think it's something similar.
