Dave learns about the downside of bachelor life when a quarantine forces him to spend a few days with Kenny; meanwhile, Beth's sister stays with the Barrys after leaving her husband.

Beth and Julie are shocked to learn their mom is still sexually active and has been spending some romantic quality time with a delivery man.

The Barrys' dinner party is even worse than Dave and Beth anticipated, as Shel tries to break up with his girlfriend, and Kenny and Julie desert the party to spend some quality time together.

Kenny dumps Julie, but Dave and Beth must break the news to her, which leaves Julie wanting to be ""near family"" -- by moving next door to the Barrys.

A fire forces Mia and Eric to temporarily move in with the Barrys, but the blaze that wrecked their house is nothing compared to the sparks that fly betwee Julie and Eric.
