S1, E18: While Stefan struggles to control his new situation, Elena and Jeremy are surprised by a visit from their uncle, John Gilbert (recurring guest star David Anders – 24, Heroes, Alias). Alaric has an awkward talk with Elena about Isobel. At a Founder's Day event, Stefan displays a rare party attitude and Damon's attempt to find out why Uncle John has returned to town takes an ugly turn. An incident at the party causes trouble between Matt and Tyler, and the relationship between Matt and his mother, Kelly (recurring guest star Melinda Clarke), reaches a new low. Meanwhile, Elena's effort to comfort Jeremy falls short and he decides to take matters into his own hands.
