In the present, Jimmy and Kim pay a visit to Dr. Caldera, the veterinarian of all of your neighborhood criminals. In Better Call Saul, he's mainly served as a doctor for people who otherwise cannot go to the police and an intermediary for various people in the criminal underworld.
Jimmy is picking up a drug that will essentially act like a version of caffeine, only much more potent. As Caldera puts it, he'll feel like he "drank two Red Bulls on an empty stomach."
He'll likely be using this in his scheme against Howard, but how he plans to remains to be seen.
Caldera tells Jimmy and Kim that he's leaving his side business behind, wanting to shift all his focus back to treating animals. His little black book, a coded journal of his contacts, will be up for sale when he leaves, likely into Saul Goodman's hands. Here, we find a business card for Best Quality Vacuum, a familiar sight for any Breaking Bad fan.
As they review the final details of their plan for "D-Day," Jimmy and Kim decide to head to "Omaha Beach." Of course, this version is the grass outside of the Hamlin, Hamlin, & McGill offices.
It isn't all nefarious schemes for Kim Wexler, though. After making a solid argument about her client's constitutional rights, she's approached by Cliff Main. He lets her know that a foundation that works on criminal justice reform plans to open up shop in the Southwest region and is looking for people to help. He helps get her an audience with them in Santa Fe for her to pitch herself, but it's also, unfortunately, on "D-Day."
She tells Jimmy at his office (which is becoming more and more Saul Goodman like every day), and he is as supportive as can be, telling her that he can manage everything and she needs to go to the meeting.
Kim agrees, but on "D-Day," they encounter a huge obstacle: The mediator for the Sandpiper case now has a broken arm. Jimmy had been busy trying to fake a photo of him using a double, but the broken arm was a new obstacle that they can't overcome on that day.
Jimmy calls to let her know as she is on the way to Santa Fe and says that they can regroup and do everything another day. However, Kim's desire to get back at Howard (for a myriad of reasons but also because she wants to fund her potential new firm) wins the day, and she drives back to Albequerque.
"It happens today," she says, and the scheme against Howard presses on.
