Theo had the reflexes of a cat and the instincts of a keyed-up army vet and immediately reached to steady Charlie as soon as he appeared. He managed to make sure that Charlie was on firm footing and not about to fall without touching him too much at the same time and returned the smile he was given when Charlie was right again, giving him some space by stepping back a little. "Not a problem." he said in response, still ready to move if Charlie fell but trying to look like he wasn't. "The leg made it through okay?" he asked, unsure if Apparating with a misaligned prosthetic was as dodgy as it sounded. "Do you want me to get the door for you?" he cringed a little inside as that last one fell out of his mouth, still not meaning to baby Charlie but not wanting him to struggle needlessly either.
