Locke turned in the direction of the voice, and saw the other man standing there. For some reason he didn't feel scared, or panicked, maybe he was in shock even he didn't know - despite this he nodded and a smile spread across his face.
"Oh," he said, taking a deep breath and looking back at the car, and then the wheelchair. 'You can't tell me what I can't do,' he thought in it's direction. He turned his attention back to the other man. "I'm doing just fine, thank you."
He could walk. Unless this was some sort of very realistic dream, the fact he could walk was really all that mattered. He didn't think he was dead, he was just...somewhere else, he wasn't sure why or how - maybe this man did. Maybe this is what Locke needed, maybe this was a second chance, after everything he'd been through in the past several years he did deserve it.
