Now I am not saying that she didnt have a bit of a hard time with the whole ordeal but lets be serious here.  Archangel, Gambit, and Sunfire are all still suffering from the after effects of being transformed into Horsemen of Apocalypse and whats Polaris doing? Tripping around space fighting cosmic wars!  Not that fighting cosmic wars is an easy job but she doesnt seem to be held back or challenged during it because of her experience with Apocalypse.

To be fair, Gambit has only recently started to showing signs of the Death persona again.  He changed back to normal so quickly too.  It's only because Mike Carey didn't want to ignore that story, and address it as possible character development that it's been picked up on again.  So who knows... maybe Polaris could suffer the same lingering effects later on?

Polaris had so many mental issues way back, i think its refreshing to see her act "normal" for a little while.

I think the same about Wolverine as Death. He just seemed to walk it off, where Warren has been afflicted with it endlessly.

I think it's one of those things they're choosing to ignore, I guess.

I'm hoping Peter David eventually addresses this in X-Factor. As well as her celestial tech.
