Keith...
[God. He doesn't deserve you. It's always going to be his kneejerk reaction, he fears, and he knows Keith wouldn't agree, but-- even if he can't quite accept the words for himself, he trusts that this is what Keith feels, that this is who Keith always has been.]
Thank you. I-- Thank you.
[What can he say but that? Keith's right. They have each other. If even through all this, Keith still wants to be by his side, then-- he isn't exactly selfless enough to push him away just because he thinks that's "right." He knows it isn't. He knows that he owes too much to Keith as it is, something he'll never be able to repay and not just because he knows Keith doesn't see it as needing repayment.]
