"Conceal don't feel, don't let them knooooooowwwww...Well now they kno-OOOOwwwwwwwch! Natasha, why did you do that?"
"Rogers, you know that I hate that song. And you sing it all the time. I know that you and Bucky were Disney buffs back in the day, but that doesn't mean that you can just dance around the Tower singing that stupid song."
"I am aware that you don't like the song, but come on, the voices and lyrics are sooooo much better now. Back in my day, we had Snow White, who sounded like a prepubescent boy singing a song on helium. While plugging his nose."
"...You win. But that doesn't mean that I am gonna stop hitting you when you sing."
Later that day:
*KNOCK KNOCK KNOCK *
"Come in!"
"Oh, hello, friend Tasha."
"Do not call me 'friend Tasha,' witch. I am still mad at you for that whole secrets fiasco. I am not your friend."
"Hokay, friend Tasha. Vell, I came to tell you somethink. Steven has introduced me to an amaaazzzing movie! It's called Frozen. You probably aven't heard of it."
"Believe me, I have."
"Vell, Steven showed it to me, and he taught me how to sing a song from it. It is called Let It Go. He said it ees not very popular, so I should sing it to you so you can hear it. Za chorus goes like zees: LET IT GO, LET IT GO, CAN'T OLD IT BACK ANYMORRRRRE, LET IT GO, LET IT GOOOOOO, 'URN AWAY AND ZLAM ZE DOOR! I DON'T CAR-"
"ROGERS!"

**Over the Intercom***

"Bwa ha ha. Revenge is mine. And, I broadcast your wimpy-ness over the intercom so that all the Avengers (plus employees and Pepper) will know that the Widow always wins."
