"Stay out of the way, who do you—" Leah barely moves forward at all before Seth rounds on his sister with an exasperated growl, the first really wolfy thing he's done.

"Leah, go back to the pack," he orders, scowling and pointing. "Just, go on, it's just Jazz, I'm fine, I don't need backup, go tell Sam what's happening."

Leah gets in Seth's face immediately, and Jasper doesn't move a muscle, attuned carefully to the emotional state of both wolves. Seth's irritation and embarrassment comes on more than one level, likely as a little brother and as a leader, and Leah's anger is resentment too, and he doesn't think it's just the old usual resentment aimed at him and his kind. That's something to keep an eye on.

Seth matches his sister toe to toe, though, unblinking, and almost before the conflict becomes a conflict at all Leah takes a step back, darts an angry look at Natasha and a look of loathing at Jasper, and turns to sprint for the woods. She's a wolf before she makes the trees, and the rustling of leaves is finished only a few seconds later. Seth sighs a little and turns back to Jasper, but he shakes his head.

"Don't worry. We're still what we are. But now that it's just you, there is something else you should know." Jasper glances at Natasha, and back to Seth. "The Volturi are coming, sometime soon, and before they get here, she'll be changed. At her own request."

Before Seth can react more than his gaping stare, Jasper tips his head toward Natasha, leaving the floor to her for the explanation, however much she wants to give. It's not exactly the same situation as Bella's had been, but if this is going to be a problem for the pack, they need to know now.
