I've thought that he might be from the Falkland Islands [off the coast of Argentina]. That's just because once he đã đưa ý kiến that a British friend of his lives in the west coast. The Falkland's are a British Colony. Also, I think he once đã đưa ý kiến that his country was at war with the British and that his country won hoặc something along those lines. The Falkland's had a lot of conflicts between Argentina and Britain. I'm not saying that it was a real war, it may have been a spiritual/moral one. But that's just me and I hope that made some sense, haha.
I think he is Argentinian because in season 4 episode 24 He đã đưa ý kiến that british people dont like his type of people and ended up saying that they won the war which may be the islas malvinas war.
