It could also have been the moment immediately following that, where Thor introduces Rogers to Groot and we get the great “I am Steve Rogers” moment.
There are numerous suggestions in the tweet’s comments trying to guess what scene is being reviewed here.
It could be the scene where Thor makes reference to Steve Rogers copying his beard, probably the funniest direct interaction between the two characters in the film, and thus a pretty good guess.
Of course, adding to the humor, in this case, would be the fact that Chris Evans would have been talking to nothing, as Groot wouldn’t be standing there until post-production was finished.
