Here is the big picture in all of this. This doesn’t make it canon that this means she has a crush on him. At best, this is like….. when a high schooler says to someone “ooooooo you have a crush on them” but they didn’t confess to AND they actually don’t (as much as we know). As of now, this is pure “writers teasing the shippers” at best. Yes, Spike teased and Angel teased but here is the big question that keeps it from becoming canon……… did this came from either Flutters or Discord? You know, the two people in this famous ship> If not, then it isn’t canon. Until either one of these two confess, then it isn’t canon. No “what’s”, “if’s” or “buts”. Because two character teasing it doesn’t make it canon, that isn’t how canon works.
