This episode reveals the origin of Domingo's nickname, "Krazy-8".
The last time that Jimmy and Nacho were in a scene together was in Season 1, Episode 3 Nacho (2015).
The hand Lalo reveals to be bluffing is the same hand Walter White was bluffing with in Crazy Handful of Nothin' (2008). Also, in Nobody (2021), it is the same Hutch Mansell (played by Bob Odenkirk) has tattooed in his wrist. This, 2-7 off suit, is the worst hand you can get in Texas Hold'em Poker, being the chances of winning extremely low.
"Into every life, a little rain must fall" is a phrase from a poem by Henry Wadsworth Longfellow called "The Rainy Day".
