I'd blame myself. I'd think I'd have failed you all. [There's no sense lying about that - he knows what his reaction would be]
[Even if he understands what he feels, though:] But you'd tell me this, too, wouldn't you? That I'm worthwhile, that you care and love me... that you would do anything for me. And if -- I were to try to leave, you would stop me, or follow after me.
[he can't do that part. he won't ask that of him, but...]
I know why you feel as you do. I understand why you'd blame yourself, why you can't forgive yourself. But you are worthy to us. Loving you in return is no burden, Aramis.
