I thought about what about would have to changed, but saw your post & I agree on not adding anything yet.

Green Lantern speaks? That's about as ambiguous as when Batman said (a) Green Lantern gave him intel in "Revelation". I'm guessing maybe Kevin Michael Richardson voices John Stewart or giving the guest cast Alan Scott.
