Details like this are what I appreciate. Not thrown in your face but still noticeable and they show a lot about the characters. It reminds me of the finale of FATWS, when Bucky helped Walker up after the latter fell when trying to save the hostages. It was also Red Guardian and Walker who carried Bucky away with the group after the fight. Seeing them go from hating each other to actually being teammates has been nice. Small moments like this scene or Walker cutting the cactus to share with Yelena and Ghost are nice ways of showing despite him being much more of a jerk this movie, he still does have a heart deep down.
