Same thing maybe like when we're going to save Y'shtola. We need her half sister Y'mithra and if we've already done SMN's job quests, Tataru or someone will say "What? You already know her?" kind of like that. And also I think Kan-E-Senna's siblings nodded at me when they were about to leave after finished pulling Y'shtola out of lifestream because I've already finished WHM's job quests, like they've already known me.
