Well, either we've got a redeemed Loki which may not be canon, but I love the idea of Bruce convincing Loki that even monster is redeemable while in the background Clint goes from jittering and ruining the fletching of the arrow he keeps playing with to wary but calm, through to determinedly civil until at some point, Loki snaps and says something acerbic and Clint realizes that 91) it's the first time Loki's been confident enough to drop his guard enough to be snappish. ...

or it's whump-palooza. But I kind of like the first idea.
