Don't remind me of Kramer...I dunno, other than his future kids, nobody seems "field ready."
I don't know if they'd make Caitlin Frost again after they spent so much time separating them, at least individually.And since cold powers run in the family, wouldn't be surprising for Caitlin to end up a "Frost" herself.
Now I just imagine Caitlin going mad scientist trying to find a way to revive Frost.
