A hunter who specializes in Fae shows up in Beacon Hills and is absolutely convinced that Stiles is a Fae because he
Doesn't go by his real name
Is surrounded by supernaturals at all times
Sometimes uses magic
Double-talks and bullshits his way out of everything
Gets genuine Delight out of fucking with people
Is exactly that kind of Petty
Isn't above a bit of murder
Is always down for Shenanigans
And a variety of other things that add up to Not Human. They refuse to believe that Stiles is and has always been human, and it's a running gag/subplot where they're just lurking around, trying to prove Stiles is a Fae with increasingly ridiculous and complicated schemes, like the most intense game of Mouse Trap ever, and Stiles continuously just manages to avoid them, which they take as proof he's gotta be a faerie because no way can an actual person Be That Way, and finally they get fed up and dig up Stiles's first name and calls him by it in front of everyone, so Stiles kneecaps them with his bat.
Hunter, on the ground: I don't understand, I thought knowing your true name would give me power.
Stiles: It does, it gives me the power to beat your ass.
