On Pretty Little Liars Season 3, Episode 21: "Out of Sight, Out of Mind" (February 26) Spencer (Troian Bellisario) will finally reveal the truth about Toby (Keegan Allen) to the Liars, and we can't wait to see what happens.

We've taken a close look at the sneak peeks of the episode to see what we can learn before it airs tonight.

Spencer tells the Liars. As we see in this clip, Spencer does dish the truth to Emily (Shay Mitchell) and Aria (Lucy Hale). Presumably Hanna (Ashley Benson) is busy dealing with her mom's hit and run situation, and will be filled in later.

Emily in denial. As we see in the sneak peek above as well as this one below, it's clear that Emily is unwilling to accept Spencer's interpretation of events. As she explains to Hanna below, Toby has always been there for her, and he's the one who gave her the strength to come out. Of course she wants to believe there's more to his story, that he isn't really evil.

Searching for Toby. In the sneak peek above we also learn that Emily and Hanna (perhaps Aria too, we don't know), decide to search for Toby, presumably because Emily believes there's still good in him. However, Hanna starts to think it's a bad idea. Will Emily keep searching alone? We have a feeling the answer is yes.
 
Toby's parents? At the end of that clip, Hanna suggests Emily try talking to Toby's parents. Does this mean we might actually meet his dad or stepmom?

Spencer gets the flowers. In the clip below, we learn that Spencer is the one who receives the flowers "A" was making at the end of the last episode.

 

Spencer vs. Mona. In the same clip, Spencer warns Mona (Janel Parrish) she's "not playing around," and Mona responds by telling Spencer to take very good care of the orchids she received, or they might not make it through the night. A threat against the Liars?
 
Emily in danger. Spencer certainly thinks so. In a sneak peek that you can watch here, we learn the flowers came with a sash that says “deepest sympathy.” In the clip, Spencer reveals that the sash only has two letters that aren't shiny: E and M. AKA, the beginning of Emily's name. Spencer is very concerned, but Em doesn't seem to let the apparent threat deter her.

Ashley's fate. In other news, here Hanna gives Ashley Marin (Laura Leighton) a lesson in keeping secrets.

Maggie coming to Rosewood. Here, Ezra (Ian Harding) has some surprise guests: his baby-mama Maggie and his son, Malcolm, who might be moving to Rosewood for good.

What's Maggie deal? In a final sneak peek, which you can watch here, Maggie acts super nice, telling Aria she's not mad that Ezra found out about Malcolm. Is she one of the few truly kind people on this show, or is there more to her story?
