That last part sounds a bit far fetched but I do get a feeling that Maggie will come back. I agree with you. But remember, Supergirl doesn't kill. So how will she get rid of Reign then?

This situation reminds of the Doomsday storyline in Smallville. There, they had a gimmick(I don't exactly remember what it was)  by which Davis Bloom(Samantha equivalent) and Doomsday(Reign equivalent) were separated and then Kent killed Doomsday. [Davis Bloom still ended up dying but that is because of different reasons]
