Allura has a similar expression. "Erm... well, it was the least I could do, since it was my fault you fell." Ironic, perhaps, since her intent had been to prevent him from losing his balance.

She lowers one arm, helping to set him upright rather than drop him roughly. "What were you looking for up there, anyway? It must have been important, if you were willing to scale the whole wall to get to it." And she turns her head up, back towards the spot that he fell from, to see if she can even read the titles from down here.
