Ross may have bonded with Moses, but I still don't know wether he'd cope looking after him alone once Debbie leaves, especially if his family disown him after the shooting.
Does Ross know that Pete told Debbie about his and Emma's deal? I was never completely satisfied with their "truce", I want their feud to be over but I don't think it is. Once Ross finds out that Pete's snooping lead to this I think all hell will break loose, again.
