Clark didn't think that she would have reacted that strongly to him telling her that Jason had been harmed. Yes, it was bad. It was very bad, actually. But the sudden shock in her eyes, the sharp intake of breath; the way she looked at him, almost as though she knew exactly what it was that he had been talking about. Clark couldn't help but express confusion at the sudden reaction that followed. "I-I'm sorry? I didn't...maybe I shouldn't have said anything. It might be better for you to hear it from him." Jason would probably appreciate it more if Clark kept those details to himself. Probably? More likely. The last thing anyone wanted was for him to bring in a woman who was traumatized by the city before she was even brought through the front door of the apartment building.
He couldn't push himself to notice much of anything beyond how horrified Sookie seemed to be. Maybe it was an overreaction; maybe she just really, really cared. Clark wanted to say something - heck, anything - to ensure that she wasn't as frightened as what he saw standing before him now. The thing was, there wasn't more that he could say beyond the assurance that Jason was fine.
"I promise, he's gonna be okay," Clark tried, giving her as honest of a look as he could manage. "We have people looking after him. He's also getting a lot of rest. If he had it in him to ask after you and send someone off to find you, then that means he's getting better." Because, clearly, before that Jason could have barely managed moving, let alone holding his own end of a conversation.
Then she did it again. Something...different. Something that Clark wasn't quite used to. "Run?" The remark would have sounded absolutely insane coming from someone who was standing out in the streets with no shoes on. In fact, the way that Clark looked at her probably made Sookie feel as though he thought that she was. Clark, on the other hand, was more confused than anything. He had just been thinking about running...how did she - it was almost like she had read his mind.
"I, uh...why would you want to run?" Superspeed. Did she know about the superspeed? Does she think I'm Superman?
