since bagpipe's a bit relevant due to getting en voice lines lately, i was reminded of her dialogue where she says Reed was initially "terrifying" and it made me wonder if maybe Bagpipe initially recognized her as the leader of Dublinn at County Hillock, or at the very least, a member of Dublinn from there. but that wouldn't exactly line up with her dialogue in the Firelight event where she seems to realize Reed'd "true" identity finally. so i came up with my own theory that makes sense of both pieces of dialogue: in the Firelight event, Bagpipe was more speaking out against Reed having rejoined Dublinn (or more accurately making her "own" Dublinn in a way), which Bagpipe only saw as this organization that caused pain and sewed conflict and chaos, which we know isn't what Reed's vision for Dublinn is now. (applogies if this has gone through like 5 times, retrospring was bugging out a bit when i went to ask this)
I'll be honest, my memories are really fuzzy, but I just took her reaction to Reed in WTFC to be that she had a hard time reconciling how the Reed there could be the same Reed in County Hillock. Ch'en said something to the effect of Bagpipe not wanting to think badly of someone she likes, or approves of.
