On Monday's all-new episode of Pretty Little Liars, Holden finally reveals his secret -- but it may be more than Aria bargained for.
"I do Tang Soo Do. It's a marital art. It's Korean," he tells Aria. "I compete and my parents don't like it. They forbid me to keep training."

Holden responds dryly: "No, everyone's got teeth." After explaining that the pills are pain relievers -- and not illegal street drugs -- he then asks Aria to continue covering for him in order to compete in an upcoming tournament.
