A leak in the apartment above theirs forces Jung and Kimchee to find temporary accommodations while repairs are being done in the building. Umma takes the opportunity to offer Jung Janet's old room - Jung not having stayed since his and Appa's falling out when Jung was sixteen - while Appa is less than excited to have Jung back. Some miscommunication results in a different housing arrangement than Umma planned which affects the dynamics not only at the Kims, but at Janet and Gerald's. Meanwhile, Shannon is angry with Alejandro for breaking a weekend getaway engagement for what she considers a frivolous work issue. Shannon inadvertently takes her frustrations out on "JBT", she who tries to make amends on JBT and his creator without actually owning up to doing anything wrong.
