I'd say not at all as either of them coming second won't be a shock.
Between Jorgie and Matt it has been difficult from the outset to predict which one will win. They have taken turns at the top of the leaderboard in almost equal measure, unlike Chris who prior to the final had only been knocked off the leaderboard once I believe*. In that respect, I'd say Jorgie and Matt are more comparable with Claire and Kyran.
The only similarity to Chris and Suzanne that I can see is regards the public vote. The popularity of both contestants is a complete unknown at the moment - whereas in Kyran's year when Claire found herself in the middle/bottom half of the leaderboard she ended up in the skate off both times. In their final, Kyran came from third place on final night to win the trophy!
With no consistent leader this year, hopefully the best on the night will get the voter's backing.
*Having checked wiki, Chris was second twice, but his high scores were considerably higher than Suzanne's all through the series. Each week he topped the leaderboard, he averaged 2 points more than her, whereas when she beat him to top, both times it was only by half a point.
