Looks like I'm going to have to watch the last bit again, I was catching up with recordings last night but seem to have missed lots of significant stuff as I was wrapping pressies at the same time.
I hadn't noticed Emily's bump (or that scene at all for that matter) but it does tie in with something said in an earlier episode. When Tony was trying to get her to go back to France because he'd found more evidence, Mark was trying to stop her going saying something about not wanting a repeat of 'what happened last time'. I'm betting she was pregnant (with Mark's baby?) and went back to France on a previous wild goose chase and the stress resulted in her having a miscarriage. Hence no more children and Emily's reluctance to listen to Tony's latest theories.
Apologies if someone already suggested this as I've only skimmed the last bit of the thread.
Alain struggled so hard with sobriety, but this year he has 20 years. Present tense
Whoever said this, I just took it to be the translation from the french. I haven't done any french since my O level (nearly 30 years ago OMG) but I vaguely recall that french for 'I am 20 years old' translates as 'I have 20 years', or something like that anyway) and yes I do remember original Charlie's Angels.
