Aria continues her walk on the dark side, while Hanna and Caleb attempt to protect Spencer.

We open on Spencer getting interrogated at the police station by a colleague of Marcos.

Shes ostensibly been there for a while, and shes getting sassy.

Do you remember a joke you made to Detective Furey about burying a body?

No, but I do remember unbuckling his belt in the elevator, she shoots back.

The cop quips that she might want to wait til he asks the questions first.

Of course, then Marco comes in to play good cop, asking her if shes okay.

Thats sort of like setting fire to my house and asking if Im too warm, Spencer says.

Marco says hes just trying to help, but when Spencer keeps her lips sealed, he gets cold.

Do yourself a favor and get a lawyer, he advises.

Nothing of note here, except a creepypairof ballerina lamps… representing Mary and Jessica?

Or another set of twins we might have yet to meet?

The Liars meet to discuss Spencers, er, predicament, and understandably, theyre pretty freaked out.

Pick up my homework or go to detention, the cell phone reads.

Remember, prison food makes you fat!

I hate that thing!

Hanna thinks its her turn, but youre playing for me.Gulp.

Its a computer shop; the only danger Ill be in is being bored to death, she says.

Speaking of love triangles… Ezra has gotten back to normal quite quickly (suspiciously quickly?

and if they sell the book, it just means theyll have a more successful life together.

Hanna gets A.D.s hard drive, but theres just one thing on it a Patsy Cline song.

Caleb is confused, but Hanna gets it: A played Patsy Cline when they were in the Dollhouse.

Caleb pushes for a connection to Lucas, but Hanna stays firm in believing his innocence.

He saved me, she says.

He gave us an alibi the night of the murder.

Unfortunately, not all alibis succeed, as Spencer has found out.

She goes to Marcos apartment to plead her case, but he isnt happy to see her.

Why wouldnt he die the same disgusting way that he lived?

I mean, yeah, in an ideal world!

But… this is Rosewood.

She begs him to let this one slip through the cracks but it doesnt work.

He kicks her out, coldly.

I guess you didnt know me as well as you thought, he says.

Marco, I was rooting for you!

They plug it into the computer, and a video interview of Lucas starts playing.

Apparently, as seen in this new video, he went back alone and admitted that he lied.

He has no idea where Hanna was that night, he tells the cop.

Her friends, though?

Hes seen too many things that theyre capable of.

Does he think they did it, the cop asks?

Lets just say I wouldnt be surprised, he says.

Obviously, the Liars are furious watching this, but Hanna (weirdly?)

continues to defend him.

This strikes a nerve on Aria, who sulks guiltily in the corner during every group scene this week.

Thats not true, Aria says.

Once, you were so scared of Lucas you pushed him out of a rowboat.

I cant believe youre already flaking out on me!

Shes extra sensitive because Spencer had questioned her intentions and plans earlier in the day.

Ali throws the vitamins into her mouth and heads to work.

Another scuffle happens when Hanna heads out of her apartment only to find Mona at the door.

Still, they cant know Monas involved.

You didnt tell them I know?

How many times do I have to save all of you until Im finally part of the group?

(2) Itstrue,Mona saves them all the freaking time and no one gives her any credit.

Of course, this isnt A.D. its Aria, looking extremely A-ish in her black hoodie.

(Or are they?)

(No, ofcourseshe doesnt get a glimpse.)

So they know theres a co-conspirator.

Then, Spencer finds an earring on the ground… that matches the one in Arias other ear.

Is this her choosing Ezra over her friends, once and for all?

At the Radley, Hanna digs through boxes of credit card receipts, with no luck.

The Spencer Hastings/Archer Dunhill receipt isnt where it should be, and theyre running out of time.

There will be nothing left to find, he says.

(So did Mona push Ali down the stairs?

Did Ali make herself fall because shes trying to get rid of the baby?)

Then, Hanna sees Lucas on the security cameras, in the hallway at the Radley.

Who is he going to see?

Spencer is home alone when Marco calls.

I wonder if people would think that was strange… Vaguely threatening a cop!

Back at the loft, Lucas is rifling through his papers, searching for something.

What could he be looking for?

They only communicated by email.

Meet me at the Radley.

But no one ever showed up.

This one was done much later than the first, and turned the idea of vengeance into a game.

Hmm, sounds familiar.

They ask Lucas how it ended, and he says he doesnt know.

It was never finished.

Was our business partnership ever real?

He says hell make it back and that it was worth it… Hanna is worth it.

This is really, really depressing to me.

Its been like 10 years and poor Lucas is still ruining his life for Hanna?

Youve got to move on, dude!

Spencer and Marco sure are.

Hes the one conducting her second police interview, but theres no more Mr. Nice Guy.

Emily asks why Ali pushes her away.

I dont know, Ali says.

But Im ready to stop.

She walks toward her and says she wants to do this, together.

(Which is exactly what she said last week, sooo…?)

They kiss, and its sort of sweet but I stilldo not buy it!!!

!How does Emily not feel like a consolation prize?

Have a seance and talk to Maya!

I even liked her better with pot brownie girl from the Brew.

She settles onto the couch and starts to cry.

How long can she keep this up?

You cant just draw a scribble tree on the last page of a slick comic!

I dont even have that many burning questions this week.
