There is nothing tender in their last kiss. It is hard, bruising, grabbing, and possessive. Bittersweet, he briefly thinks that this will be what he remembers for years to come.
He pulls her in, pressing her face to his, as if he can remind her of their love, as if he can mark her as his own. Instead, she pulls away.
"Please --" He reaches a hand out, pulling at her.
She shakes her head, ignoring the tear that threatens to fall.
"I'm sorry, Hawkeye. It's over." She leaves without a word, and suddenly their apartment seems cold and unwelcoming.
