The Lying Game's Ethan and Emma are going to have a major blow-out on Monday's Season 1 finale.

"There's a fantastic scene with Emma and Ethan out at the trailer where they get into a very big fight," star Alexandra Chando tells TVGuide.com. "It's nice to see these two people who really love each other fighting finally and letting it all out."

In the penultimate episode, Emma (Chando) learned that her boyfriend Ethan (Blair Redford) had kissed her twin sister Sutton, also played by Chando. But Ethan and Emma have much more to deal with then their complicated love triangle. Rebecca (Charisma Carpenter) and Alec (Adrian Pasdar) are now engaged (after just a few weeks of dating!) and planning a hasty wedding, all while the truth about Rebecca's past and Alec's possible involvement in a murder are coming to light. "The engagement and wedding puts everyone on high alert," Chando says.
