[pietro has plenty to be angry about, he just keeps his willingness to fight the world better contained than some speedsters. his rage is more of a smoldering ember than a bonfire, and since he and wanda were ten years old, he’s had a focus for his anger and hate in tony stark.

there’s no humor in the storm clouds that gather in pietro’s expression now, quick as lightning and equally full of promised danger. he takes a scowling step toward tommy, fingers curled into fists at his sides.]

“Pretend to be a Maximoff”? Who the hell do you think you are, coming to me like this and telling me who I am not? I should be the one slapping you! My name is Pietro Maximoff - I am called Quicksilver. And if you don’t like that? You can leave, little American brat. In fact - you should leave, before I have a mind to punch you into the next dome.

[he spits lightly at tommy’s feet, flashes him a final hateful glare, and turns to go the opposite direction. is he grrr enough for you now, thomas?]
