I love you.
Most things in life--they can't be relied on, not really. I've seen far more than enough to prove that. But if two people say to each other--yes, I will love you and stand by your side no matter what, no matter what you do--you can rely on that. You can get coerced into committing atrocities but if you say 'I will love you and stay with you even if you commit atrocities' then that's something you can rely on, something you can keep, and I have not been able to keep almost anything ever but I will always have the fact that you and Imliss love me, and you two will always have me. That's something no Vala or twist of fate can ever take away.
