So, you think Ed is Norwegian? I still say Swedish... He knows Swedish, I saw it... Then it got edited out, which tells me he considered that as a giveaway...
I'd go with Swedish or Norwegian. I've ruled out Finnish, but that's about it. He could very well be a Dane. He could understand Swedish without being a Swede, and he was too quick to admit that he probably is, so I wouldn't be as quick to trust him.
