Heresy writing

Sooo...Is there a particular reason as to why in those final scenes Eris nor Drifter used stasis to defend themselves…? I’m confused as hell. It’s been a while since I’ve play destiny 2 admittedly, but I like to follow what’s going on because I’d love to find reason to return. But that scene just felt so heavy handed. I’m pretty sure they both still have stasis powers or am I mistaken? I also find it odd Eris was surprised to find herself “alive” when no one knows more about throne worlds than her, she should have been laughing in her killers face knowing she’d be back. If there’s no explanation then I am just dumbfounded at these writing decisions.
