John stood and watched, lighting a cigarette casually while he waited. He wanted to see what Bryn was going to do next. And the more he listened the more he understood. The stranger had tried to steal from her. She hadn't stopped him for a quick snack, so there was that at least. Patiently, he waited, smoking his cigarette and watching, just in case something happened. Not that he was worried about her safety. He was sure she would be fine.
When the stranger ran, John casually walked down the alley towards her. Reaching down, he picked up the fallen bracelet and necklace and held them up, looking at them. "How did a bloke that big manage to nick anything from you?" he asked, holding them out for her to take. Although it was damn tempting to take the bracelet, he didn't. It would have taken a small bit of slight of hand to do so, but there wasn't much of a point in doing so.
