flashforward: s01 e05 gimme some truth

I don't know what just happened, but I lost this whole post and I'm too tired to redo it, so we'll skip to the questions at the end.

Questions!

- Who sent that message to Olivia? There were only three people with Mark when he admitted what happened, unless someone else at the bar is a spy. Did someone else entirely know through other means, and it's only a coincidence that it happened then? And why would they send the message at all?

- Why were they attacked-- was it the President's call, or was it independent? And why are the attackers all Asian?

- Is Janice going to die? If so, that changes the future and ups the ante on the show, since the Flashes are only what would have happened then and things can be changed. Which puts Noh back in the game and totally tosses Mark out the window, since the whole Mosaic project is based on his Flash.

- That lady at the door was the same one in the picture, right? If so, why does the kid know Stan so well, while his mom is all frigid? And what did Stan "do to that girl"? And why wouldn't his wife know about it?

- What's going on in the rest of the world? The other doctor and his mystery woman, the call Lloyd got, the babysitter's drowning, all of that?

- Are the Towers still there? And if they're intrinsic tot he Flash, where are the bigger ones that would have set it off for the whole world?
