The Lying Game Episode 1.05 Over Exposed

Not only is Emma going to her first Homecoming dance, she's also running for Homecoming Queen against Sutton's main rival Nisha. Emma convinces Kristin and Ted to un-ground Laurel for a night and let her go to the dance in order to support Justin, who is running for Homecoming King. Meanwhile, Nisha exposes Mads and Eduardo to Alec but Mads attempts play it off.

At the dance Emma wins Queen and Justin wins King! As Emma and Justin begin their victory dance, Ethan (all dressed up in a tux!) arrives out of the blue and cuts in. Ethan and Emma kiss for the first time in front of the entire student body. In L.A., Sutton sees pictures of Emma and Ethan kissing at the dance, and in turn starts kissing Thayer.

Later, Emma finds a picture in the Mercer family album of her birth mother, Annie Hobbs, and realizes that she went to Arroyo High School back in the day with Ted and Alec.
