The fifth season of "Pretty Little Liars" aired Tuesday and fans are all waiting for the second episode of the hit TV series.

The DiLaurentis are all back in town for the second episode of "Pretty Little Liars". The Liars welcome Ali as she is back in town after she went to New York to blow some steam off. However, the Liars are having a difficult time adjusting with her as things have changed a lot since she left or went missing.

Ali is back and is living in the DiLaurentis' home. However, she "is still sleeping with one eye open as she is forced to stay at home with her family - who she doesn't trust." Although Ali's mom is not present, Kenneth DiLaurentis and Ali's older brother will appear in the second episode of "Pretty Little Liars" season 5.

The official synopsis of the second episode is out entitled "Whirly Girl," and Sasha Pieterse's character is struggling after coming home, especially being around the family members she does not quite trust.

"With the events of New York behind them and back in Rosewood, the Liars are unsettled to still be living under a cloud of secrets. Aria is haunted by the recent past events, while Emily, Hanna and Spencer try to wrap their head around the new normal. Alison, on the other hand, is still sleeping with one eye open as she is forced to stay at home with her family – who she doesn't trust. Meanwhile, Jason's odd behavior and Kenneth DiLaurentis' search for Jessica starts to raise eyebrows about her disappearance."

There were speculations that Alison's twin sister could be the real "A". Ali's twin sister, Courtney, could be that person that is disturbing and threatening the Liars. This could also be the reason why Ali's mother Jessica DiLaurentis was hiding her death .
