this moment is actually much more than a moment of sass. For the trainwreck that was this movie, these lines are brilliant because they DUALLY confirm his acceptance of himself, and his burial of a hatchet. In other words, this is Loki’s two-pronged detente:
1) with his inner war of self-hatred, for being a Jotun (”I’m not Asgardian,” openly directing all those witnessing his almost certain death to his true heritage)
and
2) with his outer feud against the Avengers ( “we have a Hulk,” tacitly quoting Tony Stark, and citing the moment that his worthy adversaries defeated him: people who are, in part, adversaries no more).
This was truly a seminal moment in Loki’s personal development.
This is an act of defiance, and one of heroism, for as futile as the endeavor may seem for all practical purposes, Loki DENIES Thanos’s power over him (the power of his abuser, and so many others’), by LOVING HIMSELF: EVERY part of himself.
//I know, I really wish more time had been expended on that. But that’s the single greatest flaw of Infinity War: it took on too many characters and plots, at the cost of any of them being explored with due depth. All because Marvel is greeeedyyyyy.
Marvel Parallels: Peter Quill // Tony Stark Both Peter and Tony have been carrying the grief for the loss of their mothers their whole lives, and they both have regrets on their last goodbyes. Decades later they’re still trying to find closure but only to get smacked right across the face by the truth of their mothers’ deaths, how they were mercilessly murdered, and that they’ve been living in a big fat lie the whole time. [Disclaimer: This post has no ill will towards Bucky nor Steve, I know Bucky is also a victim and is not to blame, I’m only drawing the parallels between the experiences of Peter and Tony and their reactions when they find out the truth about their mothers’ deaths]
All because Marvel is greeeedyyyyy.
