During his time in Montreal Shane always participated at the world championships whenever the Metros didn't get into the playoffs & he's got two gold medals under his bellt (including one win against team usa lead by scott hunter, sweet revenge). After he joined Ottawa, Shane was too busy winning Stanley Cups to even consider participating in the world championship, but even the best streak has to end one year and post season starts early for the Cens.
Shane's suprised why Ilya is so pushy for Shane to be part of Team Canada and join them in Switzerland, but it all makes sense when they have their first game and Ilya has the time of his life leading Shane's fanclub for two weeks (and eating his weight in Swiss Cheese). Ilya really leans into the "Oh, I better dress up extra nicely, because my rich, successful, handsome husband is taking me out for dinner" WAG roleplay thing when they go out on free evenings. But Ilya also makes sure to cheer on Luca, who is playing the hockey of his life for Team Switzerland that year, and Luca - despite having grown into a more confident person by now - can't help but blush when he sees his captain, alongside Luca's partner, hooting and hollering during his games.
The evening before the championship's finale game between Canada and Switzerland, Shane invites Luca over and they sneak on the hotel rooftop with some chilled Rivella, which to Shane's suprise is even better than ginger ale. Shane rightfully guessed that Luca is a bit nervous to play against each other, the first time since Luca was a rookie (and aside from the scrimmages), and Shane tells him that Luca only needs to be nervous if he does play anything other than exceptional hockey like he always does, because Ilya raised him better than this. Luca answers Shane's smirk with a grin of his own and says, that he won't go easy on an old man, ouch, but fair, and Shane says, good, he'd be offended if Luca did.
Later, after the tournament, Luca also takes the opportunity to invite Shane and Ilya, as well as his famous retired hockey player boyfriend, to tour around Zürich to introduce them to his parents and show them the places where he grew up and learned to play hockey, which makes everyone a bit nervous, except Ilya, who brags about how much other parents love him. But in the end they all have an amazing time, except for when Shane and Luca lose their partners - and almost one gold medal as well- to the lush Zürich nightlife
