Check out these sneak peek clips from “Pretty Little Liars” Season 4, episode 21, titled “She’s Come Undone.”

Above, Spencer talks to her parents about her drug problem. They want her to go to rehab in Philadelphia and Spencer insists it’s not needed, arguing that she’ll never get into college with Radley and rehab on her record.

Well, if there’s one button to push with the Hastings to win your argument, it’s college.

Below, Aria is determined to confront Mr. Fitz but he’s taken time off for a “family emergency.” Which we guess explains the promo (also below) where Aria is seemingly trashing Ezra’s apartment. Why do you think he’s really out of town?

Is he holed up at the cabin? Meeting with Mona? We can’t wait to find out.

“Pretty Little Liars” airs Tuesday nights at 8 p.m. ET/PT on ABC Family.
