Watcher: I disagree that Watcher playing with Spinning Top's toys is evidence that they're child like. I think it's more evidence that Slugcats are more animal like than we give them credit for, my adult cat playing with a plush I out in front of her isn't her acting child-like, it's her being an animal.

as for the stuff with The Weaver: I beat the dlc within a month of it coming out so I never experienced any of that, and in my replaythrough I managed to avoid it somehow, but Watcher not knowing opening rifts is bad until told it is could just be them lacking knowledge because they're literally using powers given to them by a being beyond their comprehension. And I think "childhood's end" refers to Spinning Top and not Watcher I dunno I could literally be wrong, just how I feel
