Loki: *brings Thanos’ corpse to the Avengers*
Everyone: Holy shit, how’d you do it?
Loki: I turned myself into an infinity stone because I know Thanos loves infinity stones, so he went to pick it up to admire it
Loki: And then I transformed back into myself and I was like, ‘mblergh, it’s me!’ and stabbed him
Thor: That’s even better than my “get help” plan, brother
