There are a couple of people here that Alcide has a very big brother feeling toward. Like, literally, a couple, as in Zee and Gracie. He can't explain it. But Alcide has always been prone to feeling however he feels about people pretty quickly. He doesn't usually try to deny it or fight it. It just is.

He likes Buffy in a completely different way. Zee is like a sister. So is Gracie. That leaves him giving a shit about all three of them. So yeah, he lets her kiss his cheek and offers her a small grin and a nod. He'll definitely have to meet Cisco.

As far as Buffy... "I..." He pauses, shoulders lifting in a slow shrug. "It's complicated, I guess." Understatement of the year. "There's somethin' there, yeah. But there's also lots of reasons why there shouldn't be somethin' there."
