The book writes: "Ilya felt like he was watching all the worst things about his life getting sucked up by a tornado" after the Skip kiss. The show translate that line visually by panning the camera around Shane, Ilya, Scott, and Kip like a tornado.

A very small detail: Scott seems to lose his smile for a split second after Kip mentions watching the game with his dad the year before, as Scott's parents has passed away when he was 12.

At the cottage, post-blowjob with Hayden still on the phone (Shane really trusts that mute button, doesn't he), Shane almost slips up and says: "I just had se—" before catching himself: "Someone's at the door."

Shane’s go-to words when lying are "sure" or "for sure", which he says in S01E01 when Ilya asks whether he wants to 'forget about it' and in S01E05 when Rose asks if he likes kissing her.

In S01E01, Ilya struggles three times to light his cigarette, but the moment Shane appears, he successfully lights it on the first attempt, symbolising the spark between Shane and Ilya.

At the 24-minute mark in S01E04, Shane jumps off Ilya’s lap after Ilya calls him with his first name. And at around the 24-minute mark in S01E05, Shane climbs back onto Ilya’s lap to comfort him as Ilya is crying after talking about his family.

Cheeky text exchange revealed at the Winter Olympic:
Shane: "Use the back entrance please."
Ilya: 😈
Shane: 🙄

Sharing a flannel: Ilya wears it on the sofa ("never want that problem to ever go away"), while Shane wears it at the barbecue making 8 burgers.

Kip wears Scott's red New York Admirals hoodie, which is the same one Scott wore earlier in the episode.

Kip's dad actually is at his birthday party at Kingfisher, while Scott watches from outside, alone.

Ilya uses humour and sarcasm to deflect from his real feelings. But at the cottage, it seems like it's the first time he uses sarcasm to confess instead: "I have this problem, yes?", "And everywhere I go I'm surrounded by beautiful women" and "I'm always wishing these women were him"

After the tuna melt scene nap, Ilya wakes first and watches Shane sleep. But when Shane starts to wake up, Ilya quickly pretends he's just waking up too, just to make it natural, nonchalant, and not awkward for Shane.

After beating Montreal, Shane tells Ilya "See you in October" with the world's most subtle wink. Next thing we know, Ilya's arranging a photoshoot together with Shane just because.

The cottage is set in 2017, but the hockey game they play is from 2015 - the year Ilya is on the cover. The game covers of 2016 and 2017 likely feature Shane as he won two times after Ilya. He bought the old version likely because it features Ilya.

Ilya holds up the Stanley Cup in 2014 and yells in Russian: "For you, Mama!" after winning it with his team Boston Raiders.

In the S01E01 gym scene, after handing Shane the water bottle and touching his hand for a second too long, Ilya subtly mouths the word "more" to Shane.

The wall art in Ilya’s living room seems to be an abstract version of the Heated Rivalry book cover, using the team colours of Shane and Ilya’s respective teams (I also use these accent colours for this website!)

Kyle Swift, one of the main characters from book 4 Common Goal, appears in S01E03 as the bartender at Kingfisher and a friend of Kip.

The show’s co-producer, Brendan Brady, appears as the commercial director in S01E04, filming the same advertisement that airs on TV in S01E03 while Kip and Elena are in Kingfisher.

The show’s creator, Jacob Tierney, has a cameo in S01E01 as the assistant director filming Shane and Ilya’s commercial spots.

In S01E06, when Shane picks up Ilya to head to the cottage, Ilya is visibly nervous and can't get his seatbelt fastened until his third attempt after getting into Shane's car.

In the S01E04 tuna melt scene, Ilya has Shane’s favourite ginger ale stocked in his fridge, showing that he has planned the day and knows Shane’s drink preference without asking.

Shane’s 'Valencio Pocaterra' commercial is shown in S01E03 (Kip and Elena watched it at Kingfisher), and the filming behind-the-scene is shown during the opening montage of S01E04.

In the hospital scene after Shane's injury, Shane's heartbeat monitors settles at 81, which is the same as Ilya's jersey number.

When Kip buys the banana socks for Scott, there’s an Under Dark poster on the wall, which is one of the movies Rose Landry is in when she mentions it to Shane in S01E04.

In the Tampa Bay hotel scene, where Shane finally comes out to Ilya, there is a framed photo/painting on the wall in the top left corner. The building is the Choi Hung Estate in Hong Kong. The name "Choi Hung" (彩虹) literally translates to "Rainbow" in Cantonese, which is a thoughtful prop detail in a scene where Shane comes out to Ilya.
