My new favorite trope:
Two people fighting over one person who HATES it when people fight.
Person A: we make a great team, right C? *says while staring directly at person B*
Person C: oh, yeah! We all work together really well! *trying to include everyone without picking sides*
Person A: yeah, but I mean us. Like, just us.
Person C: *knows what they're trying to do but doesn't know how to stop it* oh, uh.. yeah!
Person B: Alright, that's enough.
Person A: what, you got a problem?
Person C: *panicking* guys..
Person A and B start to fight, completely ignoring C's attempts to intervene and stop it, until C yells for them to stop and says that they're DONE. With both of them!
Relationship: SQUASHED.
But then fixed, by amazing storytelling skills that I don't have!
