It's actually in the film, he walks up to the trooper immediately after capturing him and starts taking off his uniform.sansmalrst said:
Still leaves open the question: has any of that (Nik Sant capturing the Scout Trooper etc.) ever been filmed?
And: Why did he chose to disguise himself as trooper, specifically?Probably so he can stand guard and pretend to be the trooper in case his biker buddies come back from chasing that Ewok.
