Robby, reeling from his family's move from Philly to the rural town of Witwicky, finds new joy and purpose when he and his sister Mo bond with the first-ever Earth-born Transformers, Twitch and Thrash.

As the Malto family get used to its new members, Bumblebee quickly learns that his mission to train the Terrans won't be as easy as he thought.

Thrash is impatient with the family rules and convinces Mo to push boundaries.

G.H.O.S.T. Special Agent Schloder pursues Twitch after mistaking her for a Decepticon; Dot is put through G.H.O.S.T. orientation.

Robby backs out of Alex's traditional Wakwak hunt, so Alex shares his family history with Bumblebee; Twitch encounters Wheeljack.

The Terrans' erratic behavior may be reflecting Mo and Robby's anxiety about their first day at their new school.
