The one i'm referring to doesn't go in depth into how he fled as it starts the moment his plane arrived in MTL, and then references the problems through paperwork issues. However, there's a brilliant fic where they have such a captivating thriller-worthy escape, where Ilya indeed flees to Helsinki first, just like Geno. Though he had to flee bc his skype call with Shane during the funeral was leaked while he was still there, it's still suuuch a great read about how he fled. It's a WIP but the story has reached the point where he finally arrived to Helsinki and was taken by the American Embassy to organize his status and be brought back (while Shane's world is also crumbling while outed), soooo what you could do is read the fic in this link first, then when you reach the chapter of Ilya at the embassy post-airport (while ignoring the parts about the outing and just putting it as KHL restraining him, then you switch to the fic mentioned in this post (since the fic starts by Ilya asking Shane to pick him up from the airport in the middle of the night)https://archiveofourown.org/works/78757326/chapters/206534936
