Also Rex Tyler/Hourman was from Earth-2 in the comics and so if Heatwave sent him back then their must be a connection to why an Earth-2 JSA member would be time traveling with Earth-1 people. Altho it is possible that hes from Earth-1, or the Waverider can jump dimensions, but i'd like to think it's because the two worlds merge.
