The first official teaser for "Pretty Little Liars" season six has finally been released.

Last week, ABC Family teased fans with what they could expect in the first episode of season six entitled, "Game On, Charles."

The teaser opened with Mona (Janel Parrish) singing "Hush Little Baby" while locked up in an empty room.

Also in the teaser are the four liars, namely, Aria (Lucy Hale), Spencer (Troian Bellisario), Hanna (Ashley Benson) and Emily (Shay Mitchell) trying their best to find a way out of the creepy dollhouse.

Following the release of the teaser which is dubbed as #SummerOfAnswers, fans couldn't help but speculate on what one controversial note meant, Venture Capital Post.

"He's going to kill me - M," the note was found written on the wall and Aria was the one who found it.

Fans are now speculating that Mona could have written the note since she was separated from all four liars.

Meanwhile, avid fans of "PLL" are also anticipating the upcoming "Big A" reveal. In season five, it was already revealed that Charles DiLaurentis is the hooded man who could very well be "A."

However, it is only season six that the mysterious hooded man's mask will be removed.

In an interview with The Hollywood Reporter, "Pretty Little Liars" producer Oliver Goldstick guaranteed that "Big A's" identity will be revealed towards the end of the upcoming season.

However, before this happens, all the liars will first be held captive in Charles' lair.

"They're stuck in there for a period of time, and we will basically revisit that period of time through their individual traumas throughout six A," he said.

"Pretty Little Liars" will premiere its first episode for the season on June 2 on ABC Family.
