I covered a number but it was my general intention to just get across that we're working on what we need to work on, and if any merges occur you guys will hear about it from us first.

In regards to the Green Lantern film, the shot of Earth-12 was from it, but I'm yet to see any sort of confirmation tying it into the Arrowverse, given how general the footage was and didn't even show a solid, close-up character. So unless we do get this confirmation, I don't think we'll really think about including the film.
