Oh yeah. Sam definitely knew a thing or two about that temper of hers. He used to hide behind his pals back in school whenever he really ticked her off. Or he'd offer her some sort of 'hey-look-I-care-will-you-please-forgive-me' type of gift with a sheepish smile. Whatever the case, a pissed off Jessica was a bad Jessica. He'd take a flock of shapeshifters over that any day.
...of course, considering the fact that he hadn't seen her in four years, Sam may have actually changed his mind on that particular matter. Because, hey, who didn't want to see their dead girlfriend spring back to life, temperamental or not?
He drew in a breath and nodded. "Okay. One cut. That's it." He shot Ruby a nervous sort of look before he stepped forward and carefully took Jessica's arm with one hand. It felt so strange, being this close to her. Familiar. Strange. And, despite the circumstances, right. This was where he was supposed to have been for the past four years. With her.
With as much caution as possible, Sam carefully angled the knife toward her arm. If she was a shapeshifter, she probably would have booked her way around the block by now. It was a shame that they didn't have a camera or something on them, otherwise he'd be able to check her eyes for that familiar flare. Pressing the blade flat against her skin, Sam dragged the knife across the side of her forearm and made a small cut. He stared at it for the longest time, then lifted his eyes up to look at her face, searching for some sort of extreme reaction to the cut.
