I think it was
@victorskid who mentioned (perhaps in another thread) some bits about Piper during the CBC Sports broadcast. Anyway I listened to it last night. So:
1. the appendectomy was the least of it.
2. personal problems between Skate Canada and Finland GP's
3. a strong plea to female skaters to take care of their bodies and if something is wrong to get help.
I think that's about it. It was enough to convey there was a lot more going on that just the appendectomy. Also she said basically that Pier and Paul were just happy they actually made it to worlds.
