I didn't really get that impression myself. The fact that Stark is wearing the same clothes from the mansion attack when he collapses in the forrest, with the suit looking heavily damaged, makes me think he is the one who gets dragged down. Considering the circumstances, I don't see any reason why even someone like him couldn't find himself in that situation.
With the talk of there being more than 40 armors in this one, maybe Tony gives Pepper a spare suit during the attack, explaining the Lego set.
