I’d like the timing of when he begins to speak from the first clip, the sound byte of him saying “I am a highly trained resistance spy!”, but with some sort of reaction shot of someone looking at 3PO annoyed perhaps?
Don’t need to stop the scene for way too long and have Iron Man slowly roll his eyes. But there needs to be something to make the joke punch, I think. I fear most people would go “wait, huh? what did he say? That was kinda awkward and fan edity.” And then the movie quickly continues talking about important things before you can fully process the joke, and the sequence is left with a weird feel to it.
