When Data hands over the tricorder to Lore, you hear a violin and viola playing George Frideric Handel and Johan Halvorsen's Passacaglia. This was played in Inheritance (1993) by Data and his "mother", Dr. Juliana Tainer-Soong.
This episode references the scene in Remembrance (2020) where Picard states that Data has a tell when they are playing cards in a dream.
