Despite winning his fight, Scourge hesitates due to Leobreaker's words.

Lori accidentally triggers a wall tile, causing Bud and the Mini-cons to fall into a shaft. Metroplex clarifies the tunnel is for Mini-cons. Elsewhere, the Cybertron Defense Team confronts Galvatron and Menasor. Bud and the Mini-cons land in Microcity, an ancient abandoned city.
