Parsons/Parsons were the only ones who had a chance before last event at Zagreb. After the first event they needed to win at Zagreb and one of the russian teams (Morozova/Zhirnov or Yanovskaya/Mozgov, both winners of their first events) should be no higher than 4th place (if P/P win) or 5th place (if P/P came second). The most possible scenario (and the only real, IMO) for P/P to qulify to JGPF was to win silver medal (Y/M overall winners) and M/Z to come 5th.
And it almost happened. P/P scored VERY well (in fact, a bunch of PBs) while Y/M and M/Z got marked really LOW (a tons of level 1s in both SD and FD), especially M/Z. For example, M/Z FD score was 72 points (it's almost 11 points lower than at their first GP, and it was lowest BV out of top 7), and they finished 5th in FD (after even hungarians and ukrainians, who had visible mistakes). Parsons, hungarians and ukrainians also had a sudden boost in ther PCS (especially ukrainians and hungarians, up to 4 points to their last event PCS). But it was enough for M/Z to finish 4th overall, Y/M won.
Oh, and I forgot to mention that it'll be Canada VS Russia JGPF (both countries have 3 teams). VERY interesting.
IMO, it was a clearly planned action to drag any other (than Canadian or Russian) team in JGPF. But the field wasn't deep enough to drown M/Z lower than 4th place, and it was almost impossible to drown Y/M even to the second place. Other teams were so much weaker technically that it was almost funny. But the sad thing in this situation were Morozova's and Zhirnov's faces when their FD scores were announced. They were so happy right after the dance, all smiles and hugs and cries, they though they did great, and a couple minutes later in K&C after their scores were announced they looked like someone have died right before their eyes.

P.S. But it's obviously just my version. Conspiracy theory at its best
Edit: oooh, long post. I should say something on topic. Go G/P!
