Pretty Little Liars season 4 episode 18 is going to pick up from where the previous episode left off, so basically we will see more of Spencer's detective-like antics as she continues her search for the truth using Alison's stories. After finding her way to a bar near Hollis College, the school where Ezra attended and taught briefly, it seems that Spencer is getting closer and closer to the truth about Ezra's real identity. However, the dilemma she is facing right now is a double-edged sword as telling her friends (especially Aria) about her discovery might stir some serious issues between them. On the other hand, not telling them about it can certainly lead to personal dangers ahead. Don't miss the all-new episode which airs tonight at 8/7c on ABC Family.

After last week's Pretty Little Liars season 4 episode 17 "Bite Your Tongue," where we saw a very determined Spencer searching for more clues with the help of Alison's stories, and where she found out about the very obvious clues on Ezra's real identity, things are going to be very intense this Tuesday night. For one thing, Spencer is now more determined to prove her theory before presenting it to the girls. However, proving it will take much effort especially now that she is somehow overdosing on her prescription drugs because of her sleepless nights. Elsewhere, Hanna will try to figure out Spencer's secret while Emily is going to enlist the help of an old enemy, Shana, just so she could meet Alison. Amidst all this, Aria will start to suffer from the lies she made before. Watch Pretty Little Liars season 4 episode 18 stream through the free online stream link found at the end of this post.

ABC Family has dropped several sneak peek clips for PLL's upcoming episode and we learned that in tonight's show, Hanna's house will be searched by the police who still think Hanna's mom killed Widen. Additionally, the preview hints that Hanna's addiction to mystery novels is over after getting freaked out by her close encounter with the "A" last week. On the other hand, we will finally learn more about CeCe's case as the promotional clip shows Hollbrooke explaining every detail about the said case, and this will somehow give Hanna another idea on what to do this week. Then, we can see Hanna catching up on a rather ultra-jittery Spencer, who now has a problem with popping a pill every once in a while. Other things the sneak peek clips tell us include Emily's plan to make amends with Ali and her move to ask Shana for help. Don't miss the all-new episode which airs tonight at 8/7c on ABC Family.

The title of tonight's episode is "Hot for Teacher" and it's going to be a Spencer-centric one without of course neglecting our other Liars. Fun fact: an awkward situation will set in when Hanna refers to Officer Hollbrooke as "Gabe" as though the two of them are long-time buddies. This will lead Aria to raise a brow at the sight of Hanna being all that friendly and sweet with Hollbrooke.

"Hot for Teacher" airs this Tuesday, Feb. 4, at 8/7c on ABC Family. Watch Pretty Little Liars season 4 episode 18 stream using this free online stream link here.
