Aw, no worries! I wasn't too scared of things and it was interesting to have a situation that could be a bit more difficult to predict.
As far as what a "train with soup" situation would be like, I'd probably wonder if Sage realized that we did it and tried to cut the string. Looking in to what happened to Yasha to make sure things are safe now seems like a general possibility. I almost sort of wonder if running away instead of accepting him or hiding behind Sage might put enough fight in Yasha that he doesn't forget things as severely. Potentially, Yasha could know just enough to follow the string and see his soulmate, but be kind of normal about the whole thing. lol
Yeah, though, I agree that Sage staying level-headed is definitely good. I had that concern fairly early on in the loops, so I think I was just worried on how things could backfire- kind of like how we can ask Sage about "what if Yasha doesn't drink the soup" even if we can always manage it if we're being sneaky.
Funnily enough, in the loops, I don't think I ever got Yasha's 1850 line, so I was always a bit confused by that reference until I saw a let's play where someone did get it.
