The end of Season Four of 'Pretty Little Liars' may be on the way, but that doesn't mean we don't already know a good deal about Season Five.

Let's not get ahead of ourselves though, let's talk about tonight's episode 'Unbridled' (4x23) first.

As the Canadian promo (above) reveals, Mrs. DiLaurentis is acting even shadier, telling someone off-camera that Ali's death should stay just that: dead. Not to mention a possible flashback to Mrs. D and Alison together on the last night before her disappearance and Mrs. D. confronting Ashley Marin in real time for snooping.

We also get a possible look at the return of Ali's brother Jason to the show. Unfortunately though, it doesn't sound like this season will signal the end of 'A.'

As the Season 5 synopsis reveals, "In the new season of the hit drama series, the PLLs must dodge their dreaded nemesis ‘A,’ while navigating a world with Alison back in it."

Meaning Ali could be returning to Rosewood for good.

Season Five starts production this week and has a premiere date on ABC Family for Tuesday, June 10 at 8PM ET. You can catch 'Unbridled' tonight in the same time slot.
