While Jane sets out to prove her worth in The Underground, Cliff goes into “dad” mode and Niles devotes a day to Dorothy, who’s finally growing up.

The Doom Patrol (along with Niles & his daughter) are still mini-sized after their last adventure. Ultimately, Niles will have to sacrifice something precious to save the team.

As Niles and Cliff set out to find a missing Dorothy, Larry is tasked with handling Niles’ old research team when the ageless aeronauts return from space.

Dorothy finds a friend in Baby Doll, while Vic looks to win Roni back. With Rita’s help, Larry finally tries to break the ice with his family.

Niles, Rita, and Larry end up in the interdimensional clutches of Red Jack, an infamous villain who feeds on pain, while Cliff visits his daughter with Jane.
