She wasn't shooting him. While bullets didn't bother the Ghost Rider physically, it was annoying to be shot all the same. So this was a good start, as far as his encounters with other vigilantes went. He assumed she was a vigilante, as in his experience, they tended to be the type to commonly use rooftop travel. "Yes. I can talk." Whether he would choose to do so for any length of time depended on how and what she asked.
He didn't sigh, but he suddenly understood why humans sometimes had the urge to. "He would have left that woman battered and bruised, or possibly dead. I intervened." There may have been a note of irritation in his unearthly voice, but she was a vigilante. She would understand the irritation being questioned would cause. As far as what the man deserved, he deserved the agonizing, cleansing fires of his Penance Stare. But it didn't seem to be working, and that wasn't something he was about to tell a strange vigilante he neither knew nor trusted.
"Ask your questions. I will answer them, but I have much work to do tonight." Surprisingly, a fleshless skull could still manage an appreciable glare, a fact this vigilante would now be aware of. "Do not waste my time." It was neither anger nor a threat and lacked the heat in his voice either would require. It was just an honest statement. He had places to be and work to do.
