In a new sneak peek of Pretty Little Liars Season 3, Episode 3: “Kingdom of the Blind” (which airs June 19), Lucas (Brendan Robinson) finally talks! As sketchy has he seemed running around Rosewood in the premiere (Season 3, Episode 1: “It Happened ‘That Night’”), he's even sketchier when he tries to explain himself.

In this clip, Caleb (Tyler Blackburn) confronts Lucas for trying to "set fire" to Hanna (Ashley Benson) (whaaaa?). Lucas is completely dismissive, calls Mona (Janel Parrish) being "A" the "tip of the iceberg," and then making a very threatening "observation."

What is going on with him? Check out the video below to see for yourself.
