Ooph. I haven't even begun to consider the possible continuity snarl that'll be Powergirl soon, or soon again sorta? Geeze.
If her continuity is taken back to what it was Pre-FP that wouldn't be too crazy but I wonder how that'll similarly affect Atlee, who isn't a Terra in the New 52 continuity. And if she does go back to being one (if PG goes back to what her story was) would Atlee follow suit? Which would then presumably get the other 2 Terra's before Atlee back in continuity as well?
Or would Atlee's story simply become some kind of streamlined third version as neither her Pre-FP or New 52 origin can exactly jive with Karen if she's restored. Hmm.
