He moved his left hand purposefully so that it grabbed the mugger's wrist that held a knife and squeezed until the weapon was dropped. There was no escape from him even as the occasional struggling leg hit him in the thigh or side, but it was ineffective as he watched Steve move to help the woman in question. She was going to be shaken for awhile, and he made certain to give his current prey a good shake in return before forcing the man to the ground and using the grubby coat to tie those hands together.

He placed a foot on the back of the mugger's neck in warning because while he was told not to break, he would use deadly force if pushed for it. It seemed that his intent was clear as the struggles subsided as sirens could be heard. "We need to go, Steve," he called simply. Armed as he was, he shouldn't be seen by the police. It would result in awkward questions about who he was and where he had come from, and he doubted explaining that he was a World War II veteran would suffice.
