That Walter stays and waits it out with him means so much, lending a contradiction to his fears in a concrete action that would not have occurred if Walter had suddenly altered his opinion of him. Even so, his escape from the attack is slow as he keeps his gaze downcast when he answers the offer, "...'es please."

Water would do him a lot of good.

Once Walter has stepped away to retrieve the water, Benjiro pushes himself upright through his arms to stare down at the state of himself. Small swipes taken at the glitter, he tries to remove as much as he can from his clothing, skin, and hair. For the first time, he feels thankful for the wear of his facemask, as it kept the glitter out of his mouth and nose.
