With only 10 episodes left — and five months before they premiere — Screener takes a look back through the twisty mysteries and tangled lives of everyone’s favorite “Pretty Little Liars.” So join us daily as we revisit Rosewood of old. The entire series is streaming on Netflix — re-watch with us!

Up next: Season 1, episode 19, “A Person of Interest,” aired Feb. 28, 2011.

What we thought then …

“A” really ups her game by implicating Spencer (Troian Bellisario) in Alison’s (Sasha Pierterse) “death,” which means it comes out that Ian (Ryan Merriman) was in Hilton Head with Melissa (Torrey DeVitto) that fateful summer weekend, and that Ian and Spencer dated while he and Melissa were broken up.

Garrett Reynolds (Yani Gellman) is a new cop on the scene who seems friendly enough, but who is also asked to investigate the Liars by his superior, a Det. Breyer (Josh Clark), whom we never see again after this episode.

Finally, right after Hanna (Ashley Benson) gives up her V-card to Caleb (Tyler Blackburn), he makes a suspicious phone call to tell someone, “I can’t do this anymore. It’s over. I’m out.” Viewers are supposed to think it’s “A.”

What we know now…

Melissa did go to Hilton Head to get an abortion (at least, we’ve never been told that was a lie), but she and Ian were not staying in the same room. Ian was there with Alison, and Melissa confronted him about it. So Ian is not lying for Melissa, Melissa is lying for Ian.

Meanwhile, Garrett is part of Ian’s little N.A.T. Club we will later find out about, so he may seem like an ally of the Liars, but he is mostly just looking out for himself.

Finally, Caleb isn’t calling “A” at the end of the episode. He’s calling Jenna — she’s been paying him to spy on the Liars and find a key Jenna thought Alison gave to one of them, which would lead to where Ali stashed the tapes of Jenna and Toby.

Hindsight hilarity…

Not so much “hilarious,” but the Hastings wanting Spencer to see a therapist is some nice groundwork for her later breakdowns and the way that family deals with things.

Creepiest dude award goes to…

Definitely Det. Breyer, so it’s kind of a shame we never see him again. Garrett will eventually get pretty creepy, but at this point in the show, he’s still behaving fairly normally.

Best ‘A’ message…

The message is only heard and not seen, but “A” texts the girls: “Breaking news, bitches. Spencer Hastings now a person of interest in my death. — A”

Even better, the “A” tag starts to reveal the extent of “A’s” network of surveillance set up around town.
