"Episode 507 is simmering in the pot. So far, I'm adding a dash of drama, a slice of sleuthing, a little lie and a hungry, desperate kiss..."

Queen Bee Alison Returns From the Dead! Makes Other Liars Feel Insecure

TV Writer Bryan Holdman tweeted this clue on April 9. Talk about piquing intrigue!

Wetpaint (April 18) took to totally speculating on who this kiss could be about. Spencer (Trojan Bellisario) and Toby (Keegan Allen) are on the outs, since Holdman recently tweeted that Toby would definitely NOT appear in Season 5, Episode 7. "Sorry," he tweeted to fans, "I have to say it is NO."

Perhaps Caleb (Tyler Blackburn ) might lock lips with someone? We learned that he is returning to the show after his spin-off Ravenswood ended, and will be back full time. His first episode appearance will be the 100th episode. How does Caleb figure into Hanna's (Ashley Benson) already complicated love life juggling Travis and Detective Holbrook?

Execs and cast dished on that and more at PaleyFest where Pretty Little Liars is the first ABC Family show to be honored. The Hollywood Reporter caught up with the stars and crew on March 16. "She's got choices! Give her options!" Executive Producer Oliver Goldstick exclaimed.

Speaking of options, in the biggest twist of all, Alison (Sasha Pieterse) - who was buried by her own mother - returns from the dead to rejoin her Liars clique. Now alive and healthy, could she be the one getting it on? Showrunner Marlene King coyly dished that Alison's return definitely effects relationships with significant others male and female.

"Season five is shaping up to be emotionally the most complex season we've had so far," she said.

Pretty Little Liars Final Season 4 Episode: "Scarring" and "Disturbing"

Well, what about Aria (Lucy Hale) and Ezra (Ian Harding). FIrst, let's back up here, Ezra got shot in the Season 4 finale, remember? So is he even alive? All King revealed in an interview with TV Line on March 19 was "Once a stalker, always a stalker."

So who's getting that desperate, hungry kiss? Guess we'll have to wait until the ABC season premiere on June 10th to find out!
