Headcanon: After Nat gives Bucky a taste of 2005-era emo music, he gets hooked. He steals an iPod, then fills it with guitar solos and screeching vocals. He can play the opening to “Welcome to the Black Parade” on the keyboard and he’s mastered an absolutely filthy rendition of “Mr. Brightside” that makes Steve turn redder than the stripes on his precious flag. Nat is a proud momma when it comes to her tiny emo son.
