The sudden switch in his friend's tone had Nathan rubbing at his eyes, wishing he had avoided this entire line of questioning. "You're not even sure if she's not psychotic, and you're putting her up on your couch? " Nathan considered explaining his heroic and noble sacrifice, but decided that wouldn't make Isaac feel better about the situation. "What was I supposed to do? " He sighed. "Look, I'm sorry. It's just been a hell of a day. " "Right. " "No, not yet. There are Capras in DC, but none matching your girl's description.
Well, there was a girl in here like that a couple minutes ago. " Kirsten tried to hold back her excitement. Maybe she could end this once and for all right now. " "She was with some British guy. " The cashier patted her hand, as if consoling her. "But, honey, if she's your friend, get her into a program and away from that boyfriend of hers. I'd bet my youngest grandkid she's strung out on something, and I'm pretty sure he's beating her up, too. " Though she made noises of disappointment, inwardly, Kirsten was rejoicing.
Even if she wasn't injured, she could still be crazy. What the hell am I going to do? He'd start by finishing his shower. Nathan soaped his body and hair, his mind far from his task. First, he would need to figure out just who this girl was. That should be easy enough if she wasn't giving him a fake name. Next, he would have to find out where she belonged and who was chasing her. Letting her crash on his couch indefinitely was not an option. Finally, he might have to drag her to the hospital against her wishes, because if he couldn't figure out who she was, where she belonged, or who she was running from, then she could be somebody else's responsibility.
