Back in the Flash Museum, Hunter tells him he wants to help him. Wally learns of Hunter's part in his previous life and suspects he has taken his kids. Hunter assures him he is a changed man and hasn't done anything wrong. Back at the Temporal Courts, Barry believes someone is after his family and begins a pursuit after them.
