Okay so, this is gonna sound weird, so bear with me.
So Brainy got some alert about someone messing with the past, and he kept telling us about it while literally changing between different versions of himself. Not that weird for me, since I kind of know a ghost that keeps doing that mid-conversation, but anyway. So he sent us to the past, we found out some jerks were trying to kill the Justice League in their past, we stopped them, and then we got stuck in some bad future where Superman was a dictator because they helped some Joker guy set off a nuke in Metropolis. We kicked Superman's butt, then went back in time to kick Joker's butt, and then came back here.
And I'm guessing that since we stopped it, Brainy probably never sent an alert to send us to the past, so nothing probably happened now. Because time travel.
