Better Call Saul’s Vet Cameo Explains A Season 6 Easter Egg

screenrant.com:

Thanks to a Better Call Saul season 6 cameo, we now know the meaning behind one more Easter egg from Saul Goodman's home. Replacing the traditional black-and-white Gene sequence, Better Call Saul's season 6 premier opened with a clearance of Saul Goodman's house sometime in the future, and as workers rifled through the lawyer's belongings, Easter eggs aplenty were unearthed. Many were already familiar — the CC Mobile ping pong balls, the LWYRUP Cadillac, the electric guitar, etc. Others have surfaced over the course of Better Call Saul season 6 — the cuddly owl toy Jimmy tried bribing the courthouse administrator with, for instance.

In «Axe & Grind,» Jimmy McGill and Kim Wexler find themselves calling upon Dr. Caldera. First appearing in Better Call Saul season 1, Caldera is a vet by day, criminal gateway by night. Whether it be drugs, crooks, or a quick escape, Caldera can make it happen and treat your dog's flea problem while he's at it. Finishing up his latest deal with Jimmy, Caldera expresses a desire to leave criminal moonlighting behind and focus solely on animals. He reveals the source of his power is a little black book filled with criminal contacts (such as Ed Galbraith) written in a complex cipher illegible to the untrained eye. Caldera plans to start a new life elsewhere by selling this phone book for a hefty price.

One clearance worker hands it to another, who then opens the cover to reveal Caldera's unmistakable coded scrawls and tosses the book into a box alongside the CC Mobile balls
