Buffy the Vampire Slayer alum Nicholas Brendon has landed a guest-starring role on Faking It, EW has learned.

Brendon, best-known as Sunnydale’s resident outcast Xander Harris, will play Jackson Lee, a professional artist and Hester High alum who interviews art students for a prestigious fellowship. Incredibly talented yet jaded and sarcastic, he challenges Liam’s (Gregg Sulkin) ideas about art, but ultimately becomes an unlikely mentor.

The actor, whose credits also include Criminal Minds and Private Practice, will appear on the MTV comedy’s season finale.

He joins previously announced season two guest stars Laverne Cox (Orange Is the New Black) and all-girl group Fifth Harmony.

Faking It airs Tuesdays at 10:30 p.m. ET on MTV.
