Bigman probably gave a list of teams for fake claims like in world cup mini. The teams there were a mix of good and bad though so it's tough to tell if it would be a fakeclaim or not, the play up to claiming was fairly poor though.
A key thing about him "soft claiming" ronaldo was that he never denied that he wasn't ronaldo even though multiple people said he was.
"If I die tonight, its your fault". Could be an admittance on his part that he has a role people might regret not exploiting if he dies, but tbh his play comes off as generally inexperienced to the point where its hard to read what is general naive play and what might be a deliberate statement people will overlook.
I think clueless is the best way to describe his play so far. The only comment he made with any real relation to the game or his character was the one that triggered attention on him (asking if people were sick of Barcelona and Lionel Messi). Since he's new I'm inclined to think his general awkward play is that of someone not terribly familiar to the rules and hasn't read through earlier games or even properly read through this thread.
I still maintain his two votes of Pez and Nov without giving a valid reason (and admitting the Nov vote was an 'ignorant vote') comes off as highly suspicious play on his part, but his unfamiliarity with the game makes it hard to ascertain whether it was a genuine gaff on his part of deliberate play masked as naive play.
