Despite its target audience of preschoolers, this show has given us a surprising amount of homoromantic moments.
Male
Jet/Sean
- Jet, who is Ambiguously Bi, is very touchy-feely with Sean, putting his arm around his shoulder at any given moment, such as in the episodes "Ice Moon Enceladus
" and "What Goes Up...◊" - In "Mindy Pet-sits", Sean actually wants to go to space for once, to see the Northern Lights. He even gets close up to Jet's face excitement, much like how Jet himself behaves. Jet holds Sean's hand to see if he has a fever before he nervously swipes it away.
- In "Project Pluto", Sean is bummed out about Pluto not being a planet and sinks into his chair. Jet puts his hand on his shoulder, making him smile.
- The ultimate gayest moment in the series happens in "Back to Bortron 7", where Sean has a dream where he sings a soft duet with Jet. Just him and Jet are in the dream, and no one else. They hold glowing orbs, look at each other, and smile. Sean sings about how he may like Bortron 7. Sean smiles after he wakes up from the dream.
- Right after the song, Jet introduces Sean to the Holo-Room, which Jet can program to look like any place. Jet makes the room look like Little Dipper Lake, back on Earth. They go into the hologram together, completely alone, then we get this exchange. During it, Jet lies down next to Sean, and it is filled with longing looks on Sean's part:
Sean: I didn't realize how much I missed green trees and blue water.Jet: (sighs) You're right, Sean! Planet Earth is so green, and blue, all covered in oceans. No wonder you miss it.Sean: Y'know, I'm sure I'm gonna love visiting Bortron 7, but if you don't mind, I'm just gonna sit here by my Earth lake for a minute.Jet: Okay! - During the "A Scientific Town" number in "Lone Star", Jet and Sean briefly do-si-do.
- Briefly in the episode "Space Race", as the gang passes Earth in the titular race, Sean looks towards Jet and comments on how beautiful it is, while Jet gives a sigh.
- In "From Pluto With Love", the gang goes to Pluto on Valentine's Day and sings "Dear Little Frozen Pluto" to it, which is pretty much a love song. During the song, Jet and Sean dance with each other (specifically, a pas de deux). Near the end of the song, Jet leaps into Sean's arms and Sean throws Jet in the air. They also look into each other's eyes as they sing You orbit all around this heart of mine.
- Multiple times in Season 2, Jet lovingly calls Sean "Sean-zo". Sean is also the only person Jet has a nickname for. Sean likes it when he's called that, and has embraced the nickname as his own as of "Magnet, PI". Sean also visibly dislikes it when Mindy, who's female, calls him "Sean-zo" in "Mindy's Bedtime".
- During the "Ice Skating in July" number from "Mindy's Ice Rink", Jet grabs Sean and throws him in the air as Sean does a pirouette, similar to the dance they did in "From Pluto With Love".
- In "Eye in the Sky", Jet is in awe at Sean's Space Scouts uniform. We then get closeups from Jet's perspective of Sean's feet, chest, back, and hat, and tells Sean it's a nice outfit. Later, Jet puts Sean on his shoulders while riding a unicycle.
- In "Lone Star 2 - Rocket Kids!", when Sean nervously puts his Neil Armstrong figure inside of the homemade foot rocket, Jet gives Sean a tender look and pats his shoulder, causing Sean to feel better.
- In "Potatoes on Mars", Jet's idea of convincing Sean to go to Mars is to get close to his face and sing a rock ballad about how Sean has just got to go.
- In the same episode, Sean seems to rest his head on Jet's shoulder at one point during the song "Potato Changes".
- In "One Small Step", Sean is on Jet's side for once, as they are both excited to go to the Moon for their sleepover, while Sydney is initially a little hesitant. It is justified, as Sean is a huge nerd about the Apollo 11 mission. Later, when Jet goes missing, Sean is worried. He and Mindy are sent to find him. When they find Jet, Sean hugs him.
Zerk/Sean
- In "Back to Bortron 7", Zerk seemed a little too obsessed with Sean. He bats his eyes at him and calls him "adorable". He also tries to measure Sean for whatever reason and stares at him while seemingly belittling Earth.Zerk: Watching them makes me want to visit this big, blue, heavy-gravity planet I've heard so much about...
Mitchell/Jet
- Believe it or not, Jet has a fair amount of moments with Mitchell, despite Mitchell's animosity towards him (and the fact that Mitchell also has frequent Ship Tease with Mindy). In many episodes featuring Mitchell, Mitchell is usually found spying on Jet, whether it be listening in on his kid-kart plans, or trying to figure out why he is building a flying saucer. Mitchell is normally a Stalker without a Crush, but the "closer to Jet" comment below makes it seem like he does have a crush on him.
- Not even their dads are immune. The episode "Earth Camping" has Mr. Peterson and Carrot arguing Like an Old Married Couple, despite both of them already having wives.note
- In "Holidays in Boxwood Terrace", Mitchell wants to find out, yet again, if Jet is an alien. He then says that (his words, not ours) that he needs to get "closer to Jet".
- In "Treasure Map", Jet is very affectionate with Mitchell in several scenes. Also, the very fact that Jet wanted to make Mitchell happy by making a treasure chest for him.
- In "Our Sun is a Star!", Jet gets very close up to Mitchell at one point.
Mitchell/Sean
- Even though they barely had any interaction, at the very least, Mitchell seems less antagonistic towards Sean than he is to Jet and Mindy.
- In "Eye in the Sky", Mitchell, being a weather expert, decides to help Sean and the rest of the kids to determine whether it will rain or not. At one point in the episode, Sean compliments Mitchell on his knowledge and remarks that he could be a Space Scout one day. Mitchell grins very widely, and whispers to Cody what Sean said. He does a salute while a triumphant fanfare plays, but then gets embarrassed and stops.
Other:
- In "Mini-Golf at the DSA", Mr. Peterson and Mindy are the last ones left to putt. When the former misses the cup, Dr. Bergs is shown comforting him.
Female
- In the background of "Back to Bortron 7", you can see two adult Bortronian women, one wearing purple and the other yellow, sitting together at one point and going on what appears to be a date at the restaurant.
