Bucky: What, is she gonna… is she gonna bat her eyes at you in morse code? 

[Bats eyes]

Bucky: [as Sharon] Steve… kiss me. No! You just kiss her! 

Steve: Not if you don’t get the signal! 

Bucky: [Bucky spontaneously kisses Tony] Did Tony give me the signal? 

Tony: No! 

[to T'Challa] 

Tony: I didn’t, I swear!
