I will live and die by the headcanon that while Shane loves,and is loved by,likes and is liked, respects and is respected by all of Centaurs, that they are his family, friends, a massive part of his support system, and ride-or-die cheer squad, in the the way Montreal should have been, I still think that the person he actually bonds with most is Haasy.
Hear me out here, to me they share some similarities in personality - personally I also headcanon Haasy as autistic, but that's besides the point - and I can see Shane coming to enjoy Haasy's company. They would have the best time just having quiet parallel play time, each doing their own thing. I can see them reviewing and analyzing game footage together for hours as a fun activity. I think Shane would be just as much of a mentor to Haasy as Ilya - to me the joke about Haasy being Hollanov's kid isn't just about them being married, it's about Haasy's closeness to both of them, his raw talent,high hockey IQ, and his hockey style combining and evolving elements of both Ilya and Shane.
I think his demeanor on the ice when play is active is much more like Shane's,as in when that boy is locked in he is LOCKED IN,so much so that the abrupt, complete personality shift has jarred many a chirping dumbass on other teams. It's not quite like Shane but only in that it's worse because Haasy is such a precious,sweet,shy good egg with a baby face to end all baby faces, while Shane is Shane (aka a covert sassy,judgy little bitch (affectionate) ).
I think Haasy did idolize Shane as well as Ilya growing up,and once he gets over the worst of his star struck timidity I think they can frequently be seen hanging out near each other.
And Ilya would be THRILLED that is their child after all!!! Look at his hockey baby bonding with his perfect husband,the world is a beautiful place!!!🥹🥰💖💖💖💖
Here's the thing I personally don't think Shane would actually mind when Ilya calls the rookies their kids, especially Haasy. Because they kind of are,and jokes aside it clearly means something to Ilya "I love yous to every player" Rozanov,and Shane would recognize that. The Centaurs are already more of a found family and it's all light-hearted and genuinely affectionate. After everything that happened with the Voyageurs I just can't see Shane getting annoyed by any of it - overwhelmed,and confused sometimes especially during his first year with them? Sure. But annoyed? No.
And Haasy is the kind of sweet,unobtrusive, hockey minded kid that would endear himself to Shane. I think Shane would want to train with Haasy as a means of bolstering and honing not just his skills but his confidence- Ilya,Bood,Wyatt and so on are better with the social end of that but that doesn't mean Shane can't or wouldn't want to contribute and I think he'd succeed- it would also help his own healing! Here's this earnestly star struck,generational talent of a kid who is so eager to learn,work hard, please but he's still unsure of himself but unlike Shane he has a support system that wants to help him succeed without overwhelming him with the pressure of constant perfection.
And Shane who needs to remember that he is THE SHANE MOTHERFUCKING HOLLANDER, who has experienced some of the worst shit from his former team and coaches would find a lot of solace,and confidence in being able to give this to rookies especially Haasy who has to remind him of himself in some ways.
I think the only thing Shane would curtail is if other players infantilized Haasy too much (not maliciously of course),or rather if it hampered him becoming more confident in himself and his play.
Because hell yeah Haasy can make an impossible shot, he trains with the best of the best but it's still all him on the ice. And his hockey dads are so freaking proud of him.
