Beat it last night. Got a little teary eyed when Shulk and Rex gave their life force to free their kids from the cycle. Xenoblade 3's setting in general is super dark and depressing, but there was something about knowing Shulk and Rex seeing that their kids were gonna be stuck in the neverending Keves/Agnian war, presumably doomed to be reborn and die into it over and over again, that just seemed extra dark to me. It was never really addressed from their point of view, but I was still really happy that they got the chance to free them from that fate. Though I suppose I'm still not too clear on the timeline of things, if this was possibly Glimmer/Nikol's first time through, or if Rex/Shulk even knew about the soldiers being reborn again and again.
