“Pretty Little Liars” aired its dramatic 100th episode last Tuesday, and after the final few moments, we can’t believe that anyone would still choose to live in Rosewood. After the plotting, stalking, potential murder and a horrific explosion, it’s safe to say that the girls aren’t comfortable in their town either – and since "A" is back, that’s something that will be explored in episode 6, “Run, Ali, Run.”

Episode 6 of the ABC Family series will air Tuesday at 8 p.m. EDT. “Run, Ali, Run” will find the town and the five Liars trying to return to normal after the explosion that rocked Emily and Toby’s street. It’s pretty suspicious that an explosion of that magnitude at the Cavanaugh house would happen shortly after Alison’s return. The synopsis teases that the girls – especially Alison – “are far from okay.” And since the synopsis called the explosion an “accident,” it’s pretty safe for fans to assume that an “accident” is far from the truth of what really happened.

After the explosion and her nasty run-in with Mona, Alison’s uncertain about her decision to stay in Rosewood. The former Queen Bee will reportedly consider leaving for good – but it’s unclear if that means running away again, or moving out of town with her dad.

While her relationship with Aria, Hanna, Emily and Spencer might be on the rocks, Alison's departure is the last thing the Liars want. The girls are determined to help their former best friend and keep her safe as they try to figure out the person (or persons) behind the explosion.

Alison’s not the only one who is “second-guessing” her return to Rosewood – Caleb, who recently came back from a short stint in Ravenswood, is uncertain if he has a place in town anymore.

“Pretty Little Liars” fans can also look forward to seeing Ezra, who is continuing his recovery after the New York City gunshot incident. The Liars and “A” are the main reason behind Ezra’s life-threatening injury – yet the former English teacher is ready to dive back into “his research to help find answers.”

Episode 6 of “Pretty Little Liars” will air on ABC Family on Tuesday at 8 p.m. EDT. What do you think is going to happen? Tweet your thoughts to @AmandaTVScoop.
