So, as it seems that all the silver medalists from nationals got the spot (B/K in the case of pairs), there will be fight between M/G and P/K for the third spot.
But is it really a fight or are P/K there as backup in case someone get injured or implodes. The scoring at channel 1 cup implies the latter. Which is a shame cause P/K have the best lifts and have come a long way in terms of PCS this year. Unfortunately, things are very competitive.

Since they aren't really in contention for worlds, I would like to see Kadyrova/Balchenko attempt a side by side quad just for the heck of it. And I still have hope that a clean Panfilova/Rylov will wow the judges and audience to the third worlds ticket.
