Re: action;
Nikola allowed her to take the kit, holding up his hands in a traditional sign of surrender. He stood, crossing his arms over his chest, looking down at her in a mixture of annoyance and disappointment. "Relax. If you're wondering whether you're going to have to kick me and run, you're not. I'm fine. I've been feeding on what's on tap, and am in complete control of myself, serum or no serum."
Though he'd be lying if he said he was comfortable being off of it. He spent the majority of his first vampiric run on the stuff and being off it was strange. Of course, being a revamped ex-vampire was strange in and of itself, and he'd had time to learn how to keep himself in check—though she would be the first to know if he felt any sort of inkling to go flying off the rails, so to speak.
