Aldo certainly did smell that, but he didn't answer Vashti. His hackles rose and gave him a look like he'd been in a bathtub with a toaster. He stopped and stood stock still for several moments; the only movement he made was the rapid twitching of his wet nose. The dreadful-looking wolf burst from the trees with little warning and sent him into a fit of uncontrollable growling. This stranger was definitely a werewolf, but all he could smell on her was rage and saliva. Normally he'd be scuttling for the house with his tail pressed to his belly and shouting for the Ulfric. Thankfully Vashti kept him grounded. 

He had little time to wonder whether the raving wolf had been a loner who'd gotten too close to a raccoon or something, for she had lunged at Vashti. With a fierce snap of his jaws, Aldo body-slammed into the female's flank and sent the likely-rabid werewolf sprawling. His  mind was reeling. A simple shove like that wouldn't keep her from them. Sides heaving, he stepped between Vashti and the drooling mess without even noticing. 

His eyes flickered wildly around their surroundings. He didn't want any more contact with the diseased wolf than he'd already had. Hoping she was able to reason but doubting it, he struggled to send a message to her. 

[i]Leave now or I'll kill you.[/i]

He imagined that the pack would probably track down the threat and kill her later anyway, but it was at least worth a try.
