Since nobody is looking especially hurt (the biggest casualties so far appear to be mostly ducks, and now -- Hange's shin), Erwin just looks amused. Bracing his feet for extra support, he takes Levi's hand to help leverage him upwards before reaching out for Hange.

"As I've only got the one, Hange, I'll do my best."

Once everyone is back on their feet, Erwin begins apologizing profusely to the vendor, who seems pissed off enough that he prefers to chase the troublemakers away rather than allow them to help clean up. So instead he starts ushering them all in a different direction, quickly, before they make it worse, somehow.

"So...where to next, Levi?"
