Michael (Rockmond Dunbar) notices some strange behavior at a nearby apartment and turns into an armchair detective after installing a "rear window" in his home in the new episode "There Goes the Neighborhood." Meanwhile, Hen (Aisha Hinds) is dismayed when her mother (guest star Marsha Warfield) unexpectedly arrives bearing news that she's moving to Los Angeles. On the work front, the 118 come to the rescue of a man pinned under a Humvee, and a garage band that rocks out too hard.
