I dont think so. I think that the good and evil lancelot change allegiance just like in variant 1 or 2. The fact that they know each other is just an additional trick for larger groups (7P+) Then why would they explicitly say that Lancelot switches allegiance in the first two variants, but not in variant #3? They ran out of paper?
No, I think they are just stand-alone.
