The best part about Pretty Little Liars is seeing the girls hook up with people who are just plain wrong for them! Though we love the scandaliciousness of it all, we've noticed that all of this bed-hopping can be really tough to keep track of. With that in mind, we're providing a rundown of which couples are headed for a lifetime of happiness, and which couples will soon be unfriending each other on Facebook! Let the gossip begin!

EMILY AND MAYA

How we last left them: We see them snuggling up together while sharing a bed. We’re not sure if that was really what Emily’s mom had in mind when she invited Maya to stay with them. It’s not like an air mattress takes that long to inflate or anything.

What happened this week: Things are heating up! All that sexual tension finally culminates in a kiss on the lips, which happens to be in a... photo booth? Will all of their interactions involve similarly outdated technology? Maybe we’ll see them visit each other via hot air balloon and pass love letters with carrier pigeons.

Where it’s headed: Maya better not try to move too quickly with Em, or she’ll apparently have Toby to contend with. And we’re starting to sense that an Emily-Toby romance may be in the works. If it is, it would be the first time that a girl this hot has gotten with such a creepy weirdo since Julia Roberts married Lyle Lovett.

ARIA AND EZRA

How we last left them: Aria and Ella run into Ezra at a movie theatre, where her mother tells Aria how cute Ezra is. Yet another reason why it’s more fun to go to the movies with your friends.

What happened this week:
Aria, stressed out by the reappearance of Meredith, shows up at Ezra’s place, looking for sympathy but making Ezra feel uncomfortable. This is just Exhibit A as to why teachers’ syllabi should not include their home addresses.

Where it’s headed: Ezra seems to be getting wary of their relationship. Plus, we think that Aria should lose some automatic points for that blatant product placement shout-out this week. No one cares about how great your Kin is, Aria!

HANNA AND SEAN
How we last left them: Hanna and Sean are studying together, but when Officer Darren shows up with Thai food, Hanna’s mom tells Hanna that Sean needs to leave. We’re not sure exactly why Sean is dating Hanna, but we know that he isn’t with her just to sleep with her, and now it looks like he’s not just in it for some free food either.

What happened this week: Hanna was hoping that Noel’s party would be a chance to take her relationship with Sean to the next level, but to no avail. But in fairness, how does she expect to receive his undivided attention when there’s free foosball to be played?

Where it’s headed: Hanna shouldn’t be too worried. Just because you’re not having sex doesn’t mean that your relationship is doomed. Lucy and Ricky slept in separate beds on I Love Lucy, and we’re sure that modern-day couples might do it, too. Let’s see — who might sleep in separate beds these days? Maybe the Clintons? Okay, so perhaps Hanna should be a little worried.

SPENCER AND WREN
How we last left them: The two of them kissed after Wren spends a lot of time just hanging out with Spencer in her room, asking if she needs him to help tutor her or anything. Is it just us, or does Wren needs some hobbies?

What happened this week: Spencer goes to visit Wren in his new pad, where he’s crashing on a friend’s couch. For some reason, Spencer is finding out that falling for a British guy is not nearly as romantic as The English Patient made it out to be.

Where it’s headed:
We’re thinking that there may be consequences for Spencer after she plagiarizes her sister’s paper. Wren clearly thought it was romantic to surreptitiously kiss Melissa in her room at home, so let’s hope that he finds it equally romantic to sneak kisses with her while she spending time in juvie.
