I was watching Lucifer when in one of the episodes there’s a billboard for supergirl and I thought nothing of it until my brain put the pieces together that lucifer exists in the arrowverse (formerly on earth-666 pre crisis) meaning that the tv show supergirl does exist but that brought me to three questions:
1. does the arrowverse exist inside the arrowverse?
2. Is it the doppelgängers of the actual characters in the show who play them in the earth-666 show(like Kara’s doppelgänger plays Kara)?
3. does the show follow the same storyline or is it just completely different?
This has been on my mind for ages now and it’s really bugging me
