Medically speaking, Theodore was pretty sure that the benefits of real, restful sleep would far outweigh the damage to Neville's arms. But he wasn't in Neville's position, and if Neville preferred tiredness to pain, he wasn't going to argue.
However, he was starting to wonder if there was anything he could do to make it easier for Neville to stand. He knelt at Neville's feet and tried a light sticking charm on his toes, not enough to glue him there, but enough to give him a bit more purchase on the ground. It was a shame he couldn't risk putting something under his feet to give him something real to stand on.
"How's that?" he asked when he had straightened again. "Still doesn't help if you're sleeping, probably, but..." He stopped, and sighed, glancing at Zach. "I can't think of what else to do. I guess that might be all we can do." For now, he added silently.
