Ronan's right up that alley just he seemingly doesn't want anyone knowing he has a heart. Too bad for him if he ever gets along a lot with Ivar and gets him a wheelchair with a bunch of spikes attached, Ivar will know exactly who did it.

Not letting Ronan be is the only way he's made friends and/or rivals. Ivar's gonna be great for him. Or terrible, like you said. Probably both.
