The American teen drama mystery-thriller television series, "Pretty Little Liars" Season 7 will be heading to the small screen by the year 2017. It was reported that season 7 would have 20 episodes. Lucy Hale confirmed that on its upcoming season, "PLL" would be the final season.  As its season finale approaches, fans were still curious who is "A".  Will Spencer Hastings uncover "A's" identity?

"A" is the main antagonist in "Pretty Little Liars". This anonymous character kept on sending threatening messages to Alison Di Laurentis, Aria Montgomery, Spencer Hastings, Hanna Marin and Emily Fields. On its first two seasons, it was revealed that Mona was "A". On its season 3 to season 6, it was revealed that Charles DiLaurentis was the character from A's identity. After being discovered, she declares "game over".

However, as shown in previous episodes of "Pretty Little Liars" A's character began showing up. After Charlotte's murder, the estranged friends kept on receiving messages from a mysterious figure named "A". The new stalker used to put emoji's in the text messages as a signature.

There were speculations leaked on the internet that Spencer Hasting might uncover A's identity in "Pretty Little Liars" Season 7. On its previous season, Spencer has been known to defy A's identity as she wanted to ruin the evil plan of the anonymous "A". Spencer convinced Toby to work for "A" and supports on her plan.

However, Spencer would betray "A" in the end and would save her friends from danger for she knew the evil plan of "A". By this, there's a big chance that Spencer might reveal the identity of A in "Pretty Little Liars" Season 7. As its season finale is fast approaching, "A" identity will soon be revealed. Fans can't wait to know the character behind "A's" identity and why "A" kept on stalking the estranged friends.
