At that, Sarah's fingers on his chest curled slightly and she drew her head back enough to look at him. He had died right in front of her and he was attempting to blow it off? Sense cautioned that it was just an attempt to settle her and her no doubt suffocating emotional state, but right now, that combined with the indignation of not knowing he could come back to life if killed.
"Just resting," she spluttered, staring at him . "You did not just- don't think for a minute- just resting?! You were dead, Peter Petrelli, I know enough to know what no heartbeat feels like!"
Though her hand had been on his chest, when she thwapped him with the back of her hand, it was against his upper arm. There wasn't much force behind it, as even now she wasn't forgetting he'd just been hurt – dead – but there was enough.
"Didn't it occur to you to tell me about this ability sooner? I know, I know, I'm the one who said it's a fun discovery but this?" She gestured at his chest and then, though there was nothing comical about the action intended on her part, shook her finger at him. "This would have been a good thing to share sooner! A simple 'Sarah, if I die, don't worry, I'll be right back because I don't stay dead' would have been nice! It would have made watching you bait bad guys more entertaining and less worrisome and it definitely would have made this just a little easier!"
Except that it really wouldn't have, not the first time. Even had she known he would come back, sparing herself the decent into that level of grief, him dying on her kitchen floor because he was between her and the danger would still have left her crying.
"I cried." Another thwap, but this one had even less force, as the indignation was already winding down. "You know I hate crying. I thought I'd lost you, because of me, and I cried and you should have told me you could do this. If you ever do this to me again, I'll- I'll- well, I'll smack you again, don't think I won't!"
She huffed at him, the expulsion of air lifting her tousled hair off her face, her expression of indignation softened by love. She wasn't really angry with him, as evidenced by the threat she couldn't even muster much of a threat for, this was, though she wasn't openly aware of it, serving to release some of the emotional pressure that had built in her.
"All right, I'm done." She sucked in a breath and then let it out, wiping at her wet cheeks and eyes with the back of her hand. "I think."
