Irvine sees the bubble go up and turn spiky in ample time to halt his charge. He's tempted for a split second to compel Jamie to keep going and see just how sturdy the shield and its protrusions are, but he reins his neonate in; Irvine doesn't necessarily want him potentially incapacitated or killed so soon after he's been turned.

The older vampire narrows his eyes at the pair within the bubble, frustrated and annoyed but accepting finally that they're a lost cause. Jamie sidles up to his sire, meek and attentive once more, and Irvine pats his head absently.

"Go kill some people," he commands, in an off-hand sort of way, and Jamie slips off to utterly fail to harm anyone murder innocent party-goers. Irvine lingers a moment or two longer, slipping his hands into his pockets, and then shrugs at Greg and Steven before taking his leave as well.
