Pretty Little Liars (8:00 p.m. EST, ABCFAM)

I am totally addicted to this show. I understand that sometimes the dialogue might be a little lacking, and the acting could use some work…but I’m still addicted. On tonight’s episode, some of the girls’ ugly secrets come out, complicating the school’s homecoming dance. One girl’s date choice may make her life a little more difficult. And who’s

performing at the dance? 2AM Club…and no, I have no idea who they are.

Warehouse 13 (9:00 p.m. EST, Syfy)

Myka (Joanne Kelly) and Pete (Eddie McClintock) must go to Detroit after a vigilante that at first seems indestructible begins using extraordinary methods to thwart criminals.

Elsewhere, Leena (Genelle Williams), Artie (Saul Rubinek), and Claudia (Allison Scagliotti) try to move on from the past while making the warehouse a little less crappy.

Covert Affairs (10:00 p.m. EST, USA)

Tonight is the premiere of this series, and it kicks off with CIA trainee Annie Walker (the cute-as-a-button Piper Perabo) as she received a promotion as a field agent. However, her agency bosses quite possibly have an ulterior motive for the unexpected promotion. A military-intelligence agent who was blinded in the field (Christopher Gorham) gives Annie a hand.
