A new face arrives in Rosewood on Season 4, Episode 4 ("Face Time") of Pretty Little Liars, and she's on a mission to uncover the truth of who killed Detective Wilden — which doesn't bode well for Hanna, whose mom is at the top of the suspects list. 

While Hanna and Caleb try to piece together what happened on the night of Wilden's death before Holbrook and his partner, played by Roma Maffia, Spencer confronts Melissa about her involvement with "A." Will Melissa open up to Spencer, or will she try and cover her tracks? As for Toby, well, he "finds a new source of information into his mother’s death, but it only leads to more questions." Of course it does. Everything leads to more questions in Rosewood!

And Ezria fans may finally have something to cheer for when Jake tells Aria she's not over her ex. It looks like Aria's feelings for Ezra are far from dunzo — if only we knew how Ezra felt about Aria seeing other boys. 

Now, this is a live blog, so if you want to join us in fan-girling all over "Face Time's" many OMG moments, keep refreshing for the latest updates. Until Season 4, Episode 4 officially starts (at 8 p.m. ET on ABC Family!), here’s a GIF of Hanna's "waiting patiently" face — oh, and Pretty Little Liarsas told by six epic Mean Girls quotes.

8:01 — Wow. That 4x03 recap really took a full minute? Don't they realize we only have 59 MORE MINUTES TO FIND OUT WHO KILLED... oh, wait.  

8:01 — Mr. Fields is back!

8:02 — Caleb is just trying to help, Hanna. 

8:03 — Hanna is on the war path, Spencer. Watch out! 

8:03 — "Find out what it is about those four pretty girls that attracts so many corpses." Preach, Detective! 

8:04 — Did Hanna just call Ella's boyfriend the "Muffin Man"? Brb, dying. 

8:06 — There's so much tension during a Hastings family meeting.

8:08 — What did the detectives find in Wilden's bank security box? A GUN. Womp, Ashley Marin. This doesn't look good. 

8:10 — Poor Emily. This Family Services storyline can only end in heartbreak. But who doesn't love a good Shay Mitchell cry face?!

8:14 — So it was the doctor who called Family Services — not "A"! In other news, WHY?! (We also learn that Em's injury is way more serious than it seemed.) 

8:16 — "You'd be surprised what normal people do." Ain't that the truth, lady.

8:17 — Saved by Caleb — aka the best boyfriend EVER, Hanna. 

8:18 — "I will do whatever it takes to protect my mother, no matter what she did."

8:18 — And Toby is off to Saratoga for answers about what happened to his mom the night she died. See ya, Keegan. 

8:18 — "A" really knows how to hold a grudge." REALL, ARIA. REALLY?! 

8:19 — So the plan is to bring Melissa face-to-face with the mask. Interesting plan, girls... 

8:21 — That awkward moment when your new beau meet's your old beau's kid....

8:25 — Are you hurt or are you injured, Aria? Jake really needs to know. (On another note, how adorable is Jake right now?!)

8:28 — Do things ever actually get easier after someone dies in Rosewood, Ashley? 

8:29 — "There's a big difference between falling and being pushed." Oh snap. Toby just went there.

8:30 — Bravo, Keegan Allen. You are knocking it out of the park tonight!

8:31 — "There are too many good people being crushed by the heaviness of air!" This guy is cray-cray. 

8:32 — Uh-uh. Did Dr. Cray Cray just tell Toby that Ali visited his mom in Radley?! "That blond girl..."

8:35 — Spencer should narrate PLL more often. What is Melissa going to do with the mask?!

8:38 — I know this Fields family convo is super serious and all, but Emily's parents are almost comical. Run, Em, run!

8:40 — Looks like the state detectives are onto Ashley Marin. This is NOT GOOD. In other news, Caleb is still the best boyfriend ever. 

8:42 — Melissa just HULK SMASHED that mask, but why oh why did Aria and Spencer split up?

8:43 — What is Hector doing with all of those NEW Ali masks? Yet another sign Ali could be alive. 

8:43 — Wait, there are 6 Ali masks... does that mean there are 6 people on the "A" team?

8:48 — "I didn't have the heart to destroy them," says the creepy mask maker.

8:49 — Who was driving the car, Hector?! And why did Ali need the money?

8:50 — So Melissa was also looking for info on Ali... interesting. Melissa was looking for answers. 

8:51 — Wilden tried to kill Spencer on the Halloween train, not Wilden. "Somebody was telling him what to do." 

8:51 — "I've been protecting you before it started!" So Melissa WAS protecting Spencer. 

8:52 — Whoa. Whoa. Whoa. Melissa killed Wilden?! 

8:53 — "She's gone." Um, Spencer, are you going to let Ashley Marin take the fall for Wilden's death? 

8:57 — Adorable Paily scene alert!

8:58 — OK, so "A" definitely called the cops on Emily's family this time. Domestic disturbance? Really, "A"? 

8:59 — "I think my mom killed Wilden and 'A' knows it." Wait, so who really killed Wilden? We're dying to know!
