Good news! ABC has renewed Pretty Little Liars for a third season! The network ordered 24 episode which will return in June 2012, after the ending of the second season in the beginning of the year.
On the spoiler in the upcoming episodes;
When Season Two restarts according to the synopsis, Hanna, Aria, Emily and Spencer are at each other’s throats, not the best friends they used to be and Emily is shunned by the group. Also the girls will be doing community service, their sentence for being found with the shovel used to kill Alison. “They are in a lot of trouble,” executive producer Oliver Goldstick gushed about the girls. “They’re [assigned to] picking up trash. But we have yet to see a fast-food place in Rosewood, so it’s high-end trash!”
