I don't see Power Girl coming back just because they put her back on Earth 2; Conner may come back, Jay will probably be back at least he has been teased I don't see the twins coming back for years. Bart and Max I could see coming back. I don't see Christopher Kent coming back especially not if Conner is because he fulfills the same role as Jon. I think Lian and Mia are going to come back and I hope they do. Lian was always one of my favorite Green Arrow characters. I could see Mon-El coming back when they deal with all the Saturn Girl stuff.
