In "Illumination," a party for the newly formed Amanda Clarke foundation that's been headed up by Victoria brings everyone to the Grayson mansion. Even Jack, who's getting good at lying these days, and Eli, Amanda's foster brother that Emily's trying to get rid of.
'Revenge' Recap: What is Eli's Motive?
I can't say that this episode is particularly interesting since there isn't much action or butt-kicking. Other than Daniel getting a black eye.
