Luis Moncada, known for his role as Marco Salamanca, one of "the cousins" on Breaking Bad and Better Call Saul, was the fight coordinator for the boxing scene between Saul and Howard.
The first shot of this episode shows 3:17 on the clock but sideways, which looks like the word "LIE" written on it. Immediately after, Kim proceeds to lie about Lalo's death to Jimmy.
The German inscription on the plaque/momento means "With Love... Your Boys."
The English translations for the condolence cards Lalo reads from the desk are:
"Dear Margarethe,
Our thoughts are with you at this difficult time. We like to remember drinking ice wine together with Werner. We will always remember him.
Helga and Erwin"
"Dear Ms. Ziegler,
We were deeply saddened by the news of your husband's death. We would like to express our sincere sympathy. In silent thought,
Brockhoff family"
