One goodie defense when suspecting to be a target of baddie action is to give the baddies a reason to keep you around. Easy to blow up in your face but it is either that or a NK in the back...again.
My voting with Chad for mew was to get mew and others talking to try to work out the other baddie. It was a toss up mostly between mew and mboon.
No one countered Cat's claim for Link. When he said that I of all people shouldn't be voting for him after being saved. Bit of a chance that the real Link didn't see that though.
Fairly certain that you are Mario. Because there was no action from him when you were trapped.
And I'm the other goodie proven to still be around... so that leaves mboon.
