As an alien fleet approaches Under, Russel is arrested by Agent Greg and his Future Infractions Bureau for a crime he has yet to commit. The others head to the Museum of Tomorrow to try to find out what crime he will commit, but are arrested themselves for planning on breaking Russel out of jail. Gus has everyone speak in past tense instead of future tense so they won’t be caught again, and he and Russel escape with the help of Vernon, Loopy and Populah, and head to the Museum to visit the future.
