Kitty knew that it wasn't something she'd ever truly understand, she could be told what it was like again and again, whether it was Rachel or Quentin, Emma, and now Jean - she knew that the Phoenix was something completely outside of her realm of truly understanding, not the way Jean did, or the other Phoenix hosts did. And watching her try to explain just a little bit of what that was like for her, Kitty wished it was something she could have spared Jean.
Nodding as Jean told her what she'd been through after, finding her way back after the Phoenix. And what she saw in this place verses going back to Earth.
"Do you think the Phoenix can find you here?" She wondered, in this place pulled out of the reality of their lives and worlds and stuffed into this pocket universe, or whatever it truly was. More than whether or not the collateral damage would be smaller was a secondary concern, they didn't have the same tech here that they'd had back home to keep watch for the Phoenix - though all their tech hadn't done them much good when it came right down to it either.
