Tyler is forced to play a dangerous part in the ritual, while witnessing the incredible power the Travelers now possess.

When Tyler turns up at the Salvatore house with the news that Markos' plan to break the witches' curse puts Stefan and Elena in imminent danger, Damon suggests they hide out in the remote cabin once owned by Caroline's father. Once there, it becomes obvious to Caroline that Stefan and Elena are keeping a secret, so Damon comes up with a parlor game designed to expose the truth. A ghostly presence at the cabin uses violence and fire to make itself known. Meanwhile, Matt takes charge of Tyler's plan to get information from one of the Travelers, and Bonnie continues to keep the truth about the Other Side from Jeremy, despite warnings from Grams.

When Stefan and Elena escape from Markos' control, only to find themselves stranded in a remote location, Stefan gets philosophical with Elena about her relationship with Damon. After their attempt to protect the dopplegangers goes badly, Liv and Luke come up with a dangerous new strategy.
