I personally, am not a fan of this one. I don't think they really presented any romantic chemistry. Once again, it's one of those ships I just don't understand why they can't be just friends. Maybe I'm just not remembering correctly, but I don't recall any emotion towards them at all. It's more of a mutual friendship, like they trust each other but I don't think at all that Scourge would've laid down his life for Bone. Nor the other way around.
Literally why is all the fanart of them kissing-
