i just realized something and i may be wrong but
Yuuri’s SP program ends with him facing away (from Viktor?) in a gesture of rejection - “the playboy moving on to the next town”
while Yuuri’s FS ends with him pointing towards and reaching for Viktor
So the SP Viktor choreographed for Yuuri very soon after he arrived to coach him is based on the drunk banquet scene when they first met, and when Yuuri showed such ‘Eros’, because that’s all Viktor knew of him back then
But then the FS Viktor choreographed for Yuuri later on, as he got to know him better contains much more of what Yuuri is, as Viktor got to gradually know different sides of Yuuri. And he knows now that Yuuri never meant to leave him, he was reaching towards Viktor all along.
