It's going to be an interesting ride to be sure, following the adventures of Power Girl and Huntress in a world that is similar but NOT their own. But eventually down the pike after Kara runs into E1 Supergirl and Huntress runs into E1 Batman, Robin, & Catwoman, eventually I would think we will want our heroines to find their way back to Earth 2.
The premise for this thread is should this ever happen? Should our duo be stuck on Earth 1 permanently? Should they go on a 52 Worlds' multiversal travel to find THEIR earth down the road? And if eventually Kara and Helena after 5+yrs DO manage to get back to Earth 2, how many issues do we think it will take?
