– amok time: jim and spock very passionately and very horizontally wrestle in the dirt while spock is very horny. wild. they also have a discussion about vulcan reproduction
– shore leave: “push. push harder. dig it in there, mr spock” – captain james tiberius kirk
– and the children shall lead: one of the more bizarre episodes, but the elevator scene is worth it. very tender, very beautiful. one of my favorite scenes for them
– the corbomite maneuver: jim says spock gives him “emotional security” and they exchange several tender and meaningful looks throughout the episode. also, even though it’s illogical, spock attempts to accompany jim into danger
– the city on the edge of forever: jim and spock domesticity & historical au. although jim does have a serious love interest, spock is very hurt and it’s rather tragic
– where no man has gone before: i now understand why gary mitchell is the antagonist in so many spirk fics – jealous!spock abound here, mateys
– the changeling: jim grabs spock’s boob ok
– turnabout intruder: they mind meld. spock can recognize jim’s mind. spock very low-key holds kirk’s hand, with the intent of offering comfort. not good enough for you? phenomenal acting by shatner.
– the conscience of the king: i have good evidence and analysis (message me if you want to know!) but to be brief, this episode is hamlet and jim is hamlet. bones, the loyal friend, is horatio (which, coincidentally, is his generally-accepted-as-canon middle name). this leaves spock – who shows an unusual amount of emotion and concern for jim – to take the role of ophelia, hamlet’s love interest. also they do that thing where jim’s kissing a lady and they cut to spock looking sad
– devil in the dark: basically the entire episode, lmao. jim gets famously jealous over a rock.
– journey to babel: very extreme “meet the in-laws” vibes from spock’s parents. spock’s mom and jim get along famously. it’s very nice
(feel free to add more!!! please :D)
