Because you are last, there is a 50% probalbilty you get your correct seat, because before you, there are 2 seats left. If the dumb passenger has caused an unresolved chain reaction, your seat is blocked. If the reaction is resolved, your seat is not blocked.

Love the discussion! Jason14h, I hope you stay in the thread - the discussion and flow of ideas is how the problems get solved.

Fuzz, your reasoning is a little bit suspect.

Spoiler!

Yes, you are left with two possibilities - your seat is either blocked or it isn't. But do either possibility have the same probability (ie 50/50) or will your seat get blocked, say, 9 times out of 10?
