Well, particularly recently too when the rinks closed down, everyone was stuck at home looking at each other with no training to go to and there's no season in sight.
It's big deal that Avonley's parents took in her teenage skating partner to live with them. That would be like suddenly parenting a teenager when he's from a completely different culture and country.
I recall when Scott Moir and Tessa Virtue moved to Canton as teenagers on their own, they found skating families who billeted them separately. It's a pity that a similar arrangement outside of his skating partner's home couldn't be found for Vadym - but I guess that's really hard to arrange. In Duhamel and Radford's book, she spoke about billeting with families and how sometimes it was really lonely and hard - as she had to move on her own as a school kid to access training.
I think sometimes when a partnership is a big deal, the coaches will occasionally billet the out of town student - but don't imagine Igor would have much incentive to give a student his spare room. (Or if that's even allowed under Safe Sport etc any more).
I do think that teams save themselves heartache by not pursuing hopeless citizenship scenarios.
If Avonley's parents can pay the expenses of a partner, they do have options available.
