I'm sure my twin has his reasons.

[What they could be, he couldn't be sure, but if someone looked like him he was going to give them the benefit of the doubt.

He stopped walking when Arthur explained, mostly so he could have full dramatic effect when he started rubbing his temples ( even if they were hidden under the mask ). Monsters he knew it.]

Sorry, but if this involves someone named 'Lord of Murder', I'm not helping for free.

[He wasn't selfless, after all.]
