In Chapter 2 in a pacifist run Lancer is chilling with Queen outside his room.
In weird route he's in his room and he asks for a piggyback ride from Susie if you talk to him twice.
These are the two versions of post-game Lancer you've all seen, but DIDYOUKNOW that in a neutral route he says 1 single additional word? It's removed in the weird route.
