Erik watches the streets and gives any passing pedestrians a look that implies if they don't move, they'll be immensely sorry for their lack of cooperation. It seems to do the trick, allowing them an unencumbered walk back, though the entire time, Erik is glancing down towards Charles' legs with worry. "Are you fine to walk? Or should I construct you something?" It wouldn't take much, he thinks, just pulling the metal from several nearby items to bend them into a wheelchair.
