Tread Perilously returns to South Coast for another episode of Tequila and Bonetti. This time, it's the episode called "Runt of the Litter."

When Tequila runs into a girl from his past, Visiting Detective Nico Bonetti and Officer Garcia attempt to figure out why he's attached to the young grifter. Meanwhile, a notorious felon escapes custody, killing his police escort in the process. Are the two story threads related? Will Bonetti learn the secret, tragic origin of Tequila, how he took a bullet, and become a deputized member of the South Coast Police? Also, will he shoot another child?

Erik and Justin once again face the heart of madness as they see dry runs for both Baywatch and Prison Break within the episode. Special guest star Robert Knepper (aka T-Bag) leads them down a dark path. Justin notes the problem with Bonetti's attempts to roust a sex worker. Erik immediately gets lost in one of his geography corners and credits for Allison Pregler for important beach terminology. Paul Kersey-isms return while Justin becomes the host of "KPFK Crackhouse." Bonetti's obsession with making pasta comes into question. Erik ends up revealing his favorite Christopher Nolan film and Justin keeps forgetting when Comic-Con happens. And on an unrelated note, Alan Moore returns.
