I am not quite sure the pacing on this episode worked fully. I think the Jasper confrontation needed a little more meat on its bones? I got the impression that Jasper was lonely and seeking what she's been taught to value, power, via fusion, but somehow it didn't quite land the way I wanted it to, maybe because it came so late in the episode. I'm impressed they're trying something this complex with the black-hole abusive relationship, again, and I think it was almost there. Or it's just fatigue talking. I dunno.

(S.S. Misery, indeed. Whether "loves company" or Stephen King, I see what you did there.)
