Pretty Little Liars season 4 episode 20 is to air tonight amid the Winter Olympics telecasts and following its very successful noir-themed episode last week. Show fans will really enjoy the upcoming episode as it is going to be very dramatic given Spencer's dependency on prescription pills and Ezra's move to destroy our poor detective's credibility. But wait it seems that the show has already forgotten about the search for whoever is buried in Ali's grave. We just hope Hanna has something in store for us tonight.

Last week's Pretty Little Liars season 4 episode 19 was an insanely beautiful episode all thanks to Spencer's creative and delusional mind? With her pill addiction taking a toll on her mind, we saw everyone and everything in black and white - literally. The special episode ended with our dear girls finding out that Aria is unfortunately reunited with Ezra. Now, how are they going to tell their friend about Spencer's quite logical theory? But it seems that the girls are willing to give it a try in the upcoming episode. We just hope Aria will take in what they have to say before someone else poisons her mind.

The trouble in the all-new episode is the fact that the girls will have a hard time explaining to Aria everything that Spencer has found out about Ezra's real identity. "Certainly there is no way this is going to be kept from Aria," executive producer Joseph Dougherty told TV Guide recently. "It's just a question of how she's going to find out, what she's going to find out and how she's going to react. We didn't say it frivolously when we said it was the season of answers, so you'll come away from the end with a tremendous amount of information." Looks like the big reveal is just around the corner, but Ezra might have prepared some tricks to divert Aria's attention as spoilers revealed that Ezra will orchestrate something that will lead everyone to doubt Spencer's credibility. Catch the upcoming episode when it airs tonight at 8/7c on ABC Family.

ABC Family has dropped a number of teasers for Pretty Little Liars season 4 episode 20 titled "Free Fall," and based on what we have seen so far, Mona and Ezra may have been working together in the past and now Mona wants to back out from whatever deal they have made. On the other hand, we will also see that Mona and Mike are still together. Another preview hints that the girls find it very difficult to break Spencer's news to Aria.

The official synopsis for Pretty Little Liars season 4 episode 20 reads: "Spencer is determined that it is finally time to tell Aria about what she has found out about Ezra, but Emily and Hanna are worried about what it could do to their friend. A wrench is thrown into the plan when Ezra tells Aria about his concern and suspicion of Spencer's recent addiction problem. Now with Spencer's credibility being questioned, can the girls trust what Spencer has been telling them about Ezra - could this all be a figment of Spencer's tired brain or really just a clever ploy by Ezra to cover his tracks?"

"Free Fall" is set to air this Tuesday, Feb. 18, at 8/7c on ABC Family. Watch Pretty Little Liars season 4 episode 20 stream using this free online stream link here.
