So.., since it's in 2040, Green Arrow Beyond?
Also, since it seems like 2 Carney's from actors who apparently have played them in this Arrowverse, is it due to time travel or alternation dimension thanks to Legends Of Tomorrow? I suppose we don't really know right now since we still have to wait for the last half of the Crisis event to air.
For the record, I've not really watched any of these Arrorverse shows, except for maybe at least 2 episodes of Supergirl, so my knowledge is limited.
Ah! Another superhero TV series from the man who ruined superhero TV series.'
Still, maybe we'll get lucky and this one will be more Batwoman than Supergirl.
