Ryan Merriman

When Five-0 nearly causes an international incident while on a case, Lt. Governor Denning tells them one of the team members will pay for it with their job.

Aria finds herself in a difficult position when trying to process Spencer and Emily's news about Jason (recurring guest star DREW VAN ACKER), while dealing with what happened at the park and her undeniable feelings for him. How could Jason be the dangerous person that her friends say he is, when he has shown nothing but compassion and vulnerability to her? With Aria waffling on her stance on Jason, Spencer decides drastic times call for drastic measures. But will Spencer's actions help Aria to see Jason for who Spencer thinks he really is, or will it only push Aria closer to Jason? Meanwhile, Hanna finds herself in a different kind of prickly situation when she tries to play nice with her future stepsister, Kate (recurring guest star NATALIE HALL - The Good Wife, All My Children), only to have things go horribly wrong. Plus, 'A' turns up the heat on Emily by trying to push her to a breaking point.

In the season one finale, now that Aria, Emily, Hanna and Spencer are in possession of the information that Alison left them, the girls decide that it's time to finally put an end to 'A' and the mystery surrounding their friend. But without certain proof that their hunch is right, how can the girls catch 'A' in his/her own game? With little more than a video and hazy memories of the night that Alison disappeared, the girls may have to turn to an unlikely source of information to help them put a stop to 'A' once and for all - or so they think.

As their doubts, fears and suspicions grow, Aria, Emily, Hanna and Spencer start to wonder what the true face of evil looks like. Is it the girl who holds a grudge and will do anything to keep her loved ones near? Is it the new brother-in-law who might have a darker side beneath the surface? Or is it an unknown stranger who is playing puppet master with the lives of four girls? Only time will tell who the bad seed is. Meanwhile, Aria views the school play as an opportunity to get closer to Ezra. But will her plan backfire and put her relationship in jeopardy?
