pll_s4ep21 - 4

You've seen the promo photos, you've heard Aria's going to lose it...now E! Online shares an exclusive video look into Lucy Hale's killer performance as Aria on an emotional train wreck in season 4 episode 21 "She's Come Undone" - as she goes on a rampage and completely destroys Ezra's apartment (perhaps after trying to hunt him down at school, in one of these sneak peeks here?).

Although King describes this scene as "heartbreaking to watch" she hopes that all PLL fans will appreciate Hale's raw emotion and commitment to the moment. "You can't look away," the showrunner said. "It's like a train wreck, you can't look away."

As you watch the clip, you might notice snatches from Ezra's journal as Aria flips through - well, E! has taken the liberty of rounding up all of the glimpses up for us:

On Jason Dilaurentis:
"Apparently Jason DiLaurentis is becoming increasingly suspicious. Not only was he drunk the night that Alison disappeared, (and unable to account for his actions or whereabouts), but now Jason's a possible suspect…Aria recently learned that Jason was taking voyeuristic pictures of her and potentially tracking Aria's every move."

On Caleb Rivers:
"He's tech-savvy and rumored to be able to hack into cell phones, which may be the way Jenna is observing the girls. Whether or not Caleb's working with Jenna, his technical skills could come handy."

On Mona Vanderwaal:
"Mona is now locked up…Mona's not "A"…"A" is still making their presence known…Is Mona working for this person?"
