Avengers: Infinity War - 10 Secret Details Revealed Since Release

1. Groot's Last Line

You've really got to hand it to Marvel: even if it turns out that the ending of Avengers: Infinity War DOESN'T turn out to be a permanent thing (or even plays out over several films in Phase 4), they still managed to pack in a hefty emotional punch in the climax.

Peter Parker's "I don't want to go" was pretty hard, Bucky's "Steve" was likewise and watching Rocket have to witness Groot dying for a second time in three movies was just cruel. The little raccoon sitting devastated on the tree trunk while the other survivors tried to process what had happened is one of those images that will burn into the audience's collective consciousness.

And now, thanks to James Gunn, it's even more upsetting than it already was. The director has revealed that Groot's last line is about the single most heartbreaking thing to ever happen in a comic book movie in an exchange with a fan on Twitter...

Well, that's soul-destroying isn't it?

There are hints throughout Guardians Vol 2 that Baby Groot and Rocket's relationship is an inversion of their dynamic in the first movie, with Rocket taking on more paternal instincts despite his internal drive trying to make him alienate himself. And in Infinity War, we see Peter Quill in an almost maternal role (when Groot "swears" at him over his games console) and Rocket then steps in to more aggressively berate him.

Rocket is basically Yondu to Groot's Peter Quill - thrust into the role without the experience to know how to do anything right, and only really able to show an acknowledgement for their relationship at a devastating final moment. And just as "I'm your daddy" was Yondu's heart-breaker, Rocket's reaction to Groot's last line was just pain in motion.

Suddenly got awfully dusty in here.
