Trivia

 * This is the second episode filmed on a train heading to the San Francisco area, the first being in "The Terminator Decoupling" (S2E17).
 * The idea of taking a train to Napa Valley was previously suggested by Raj for Howard's bachelor Party in "The Stag Convergence" (S5E22).
 * The idea of double date of Sheldon, Amy, Howard and Bernadette was previously suggested by Amy in "The Recombination Hypothesis" (S5E13) - although finally it turned out to only happen in Leonard's day dream.
 * Previously Leonard and Penny have intended to make out on Sheldon's spot in The Pirate Solution (S3E04) but that time they are interrupted by Howard.
 * A probable reason why Sheldon prefers to take a train with a pocket watch can be found  in The Shiny Trinket Maneuver (S5E12): in that episode Sheldon bought himself a pocket watch and commented "I look like a train conductor" (with the pocket watch).
 * This is the third time that Raj is spending all night in the telescope lab. He did this previously in The Boyfriend Complexity (S4E09) and "The Proton Resurgence" (S6E22).
 * Also, this is the second time that Raj has had to ask a couple in his friends to take care of Cinnamon because of this: Howard and Bernadette were asked in "The Proton Resurgence". In both times the couple make a careless mistake in watching Cinnamon.
 * This is the second time Sheldon and Amy have had a conversation regarding sharing a room for their trip, the first time being in "The Love Car Displacement". Both times have resulted in rejection. The first time, Sheldon and Amy agreed that "we wouldn't want to jeopardize our relationship by getting to know each other too well", with Sheldon commenting "Nothing sours a good friendship more than knowing each other's toilet routine." This time, Sheldon was a little more concerned about cautiously approaching sexual intimacy in their relationship, all while Amy had gotten separate rooms for them both. However, whether or not the rejection in this episode may somehow change after the kiss is somewhat unclear.
 * Sheldon finally kisses Amy on his own initiative.
 * Cinnamon's vet gives Raj her phone number.
 * When quizzed by Leonard, Sheldon himself does not seem to be aware of the significance of his kiss in his relationship with Amy. This is quite analogous to what happened to him in The Grasshopper Experiment (S1E08): in that episode he talked with Lalita Gupta with pleasing words, and then the two had dinner together. While everyone else were thinking he was hitting on her, Sheldon himself was not aware of it. However, in this episode, when he kissed Amy, he seemed to be aware of the kiss, yet doesn't exactly want to talk about it fully yet.
 * It is strange that Sheldon totally cannot understand Leonard's "you dog" at the end of this episode, because previously in The Herb Garden Germination (S4E20) Leonard has used exactly the same phrase on Sheldon when talking about the rumor made up by Sheldon and Amy that they had sex, and that time Sheldon seemed to be able to associate the "you dog" phrase with their sex rumor. It is possible that in this episode, he seemed to understand Leonard's comments with both his new friend and his steps in his relationship with Amy, but in a weird way, attempted to associate the banjo player's music with the term as well.
