"Um." Sam just blinked up at T'Challa as he tried to parse the words that had come out of his mouth. Normally, the other man was smooth and well-spoken, and Sam couldn't imagine him actually forgetting a speech, much less rambling in the way he did. It made him speechless, and the proposal itself stole the breath from his lungs. Sure, they loved each other - there was no denying that. But for some reason, he'd never imagined T'Challa actually expressing enough sentiment to propose to him.

"You didn't tie the other end to yourself." Very helpful, Sam. Definitely an answer.
