Ruby
I, of all people, knows how demonic power corrupts. It would twist inside you. Rot you from the inside out.
You really think that I'd be protected? You think being friends with Mikaelsons, with Loki, with people like Bo and Rose, would stop me being killed if the high and mighty Winchesters decided it? Don't make me laugh, they'd get what they want, probably with some emo and Dean shedding a single manly tear, but they'd get it in the end.
The difference between you and them is, you lied. That's what it came down to. You pushed your way into Sam's life, manipulated him, made him fall in love with you, and yes, that became real for you eventually, but it wasn't at first. You betrayed them. The Mikaelsons, they turn up with an ego, but they never lied. They never betrayed.
I've told them to not say a word to you, to stay out of your way, since anything they say seems to make you want to torture them when they never actually said anything wrong in the first place. Yes, they were cocky and egotistical when they offered to help, but it was still an offer of help. You refused it, they went away. That simple.
You want to humble them, when they've actually done nothing to you. Nice to know I mean so much to you, Ruby. Thanks, really. Now, do you want to keep going on about how you want to torture my lover, or do you want me to get back to trying to save your husband?
