With Yakov and likely his other rinkmates who know his habits, Victor’s hug is actually not an affection thing or a reassurance but an SOS call.
Guess what he did in episode 12.
“Help me, Yuri. I can’t do this. Yuuri’s retiring and I can’t stop him. I cried and I can’t stop him. Please skate your best. Please stop him from retiring. It’s still not too late right now, he still hasn’t completely decided. I can’t think of anyone who can save both of us but you.”
…………..and literally any salt I had remaining for Yurio getting the gold just vanished in the blink of an eye. GOOD JOB WITH THAT SKATE, SON.
