According to Nielsen Media Research, the episode was seen by an estimated 0.506 million household viewers and gained a 0.2/1 ratings share among adults aged 18–49.
The episode received extremely positive reviews from critics, who praised the humor, character development and performances.
Maggie (Jamie Denbo) returns from her maternity leave and puts Hank and Britt in contact with married couple Beth (Stacy Edwards) and Dale Komack (Chris Bruno).
Dying of terminal cancer, Beth requests that they track down a missing heirloom ring, which she hopes to leave for her son to someday use in his marriage proposal.
Dale mentions that their maid’s brother may be responsible, but as the pair leaves, Dale reveals that he gave the ring to his lover, Paolo (T Lopez) — but Paolo broke off their relationship when Beth outlived her original prognosis and refuses to return the ring.
They track it from a flea market vendor to a junkie to a medical marijuana grower, coming to realize that Beth actually bought it back and knows of her husband’s infidelity.

The writers keep pushing the character arcs along even as Hank and Britt work a standalone case, and the more we get to know these people, the more we care about them – and the more it hurts when something happens like Katie's slip after karaoke night.
