After seeing Marvin blissfully enter retirement, Grandma Huang decides it's her turn to retire from.. something. Yet when Louis fails to celebrate her the way she wants, it will take a visit from Hurricane Gene, and maybe a hot tub, to make things right.

It's Halloween again, and with Eddie getting closer to college (maybe), the Huang boys are determined to find a group costume they can all agree on. Meanwhile, Louis decides this is the year he'll finally show Jessica why his favorite spooky holiday is so great.
