After locating the bunker in which Adam was imprisoned on The Family, the police ask Claire (Joan Allen) and John (Rupert Graves) on Sunday's episode if they would allow Adam (Liam James) to revisit the scene of his 10-year imprisonment.
The third episode will "answer a lot of questions about where Adam was and what led to Hank's [Andrew McCarthy] arrest," creator and executive producer Jenna Bans tells TVGuide.com.
