Clint: What’re you talkin’ about, ‘Tasha? You come in outta nowhere after all these weeks… and read me a dear John letter just like that? There’s gotta be some reason… something!
Natasha: Nothing that I can say! Nothing that won’t hurt even more than a simple goodbye!
Clint: Okay, lady. I’ll let you go, and I won’t try to stop you… and all you gotta say is that you never loved me!
Natasha: If that’s what it takes, then I’ll say it! I never loved you! Never!
And so their relationship ended as it began— melodramatically.
