"What he's trying to say," Stiles took a step forward. He put a hand on Scoot's shoulder in a show of solidarity. He had his friend's back, no matter what. Because there was a very real chance this could go south. If it did, Stiles would go down with Scott. He wouldn't walk away, or take the chance to save himself if it came to that. He might not be a werewolf, but he was a werewolf's best friend, and a werecoyote's mate. He was pretty much in the middle of it.
"We've never encountered zombies for real. But...but we know a little about strange things. Werewolves, mainly." Stiles figured he'd put the idea out there, see what kind of reaction that got, before telling the guy that Scott was a werewolf. Rick seemed like a decent guy, like the kind of guy who would consider the information before making a rash decision. Stiles hoped he wasn't wrong about that.
