Aren't the body/mind the only pair (or single ones) that want/allow for some amount of mixture? MC "might" have an issue with that going forward because he isn't 50/50 he is 75/25 (or something like that)I had considered Body, but then her concern about MC not being pure/balanced enough
It's been pointed out multiple times since charlie was introduced and even more so when she was shown to have a connection to shopkeep that it is undoubtedly weird/ a possible hint at some connection. I personally think that the rest of SIN being introduced only furthers the weirdness between MC and Charlie. The "kids" at SIN all know that MC is important/relevant to Ella's plan (shen explaining to moon twins to not kill MC) and even Cole who has reason to "hate" MC (gonna steal ella from him) isn't as "rude"/"unreasonable" as charlie. Think about when Cole taunts MC that without SIN fighting valravn first there would be no way for MC to win, if you say oh thanks then Cole is taken aback (sprite changes to the one with shocked face) and more or less drops it after Zara says your welcome. Even I think charlie would have been more rude than Cole there.
I can't recall but does shopkeep makes an attempt to stop calling MC charlie when MC and Charlie are both at the store? Or it maybe just seemed to happen less after? If that was an intentional change then what about shopkeep in the dream didnt they call MC charlie though? I could be confused, and even if it did happen the shopkeep in dead Ella's "dream" probably isn't the "real" shopkeep like the main "path" characters
