I can understand why you wouldn't want to see him from the very little he's told me - stuck in an alternate dimension would make anyone incredibly upset. But now we're all stuck and we only have each other. We may not know each other but he makes us family - the only people in the universe who can understand each other. He's 2000 years old and I expect he's learned from those mistakes.
I believe you about the hold on pets. I don't have any reason not to.
