Flash Forward Season 1 Episode 19 Course Correction

I don't think this episode was very good, unlike all the other episodes, this one does not leave us on a very good cliff hanger. Also we haven't really learnt much from it apart from who was in charge of Janice and that Simon is needed to cause another flashforward.
Mark will not die, because I think that the people trying to kill him will be captured and told to pass on the message he is dead because at no point did we see him actually being shot. And Janice was getting a scan in her flashforawrd so she can't really have anything to do with it.
It clearly relates to a while back, when we first saw the QED's being passed around by the men with the 3 star tatoo's. They must work for “bigman” or “bigguy”, whatever his name was.
jericho must play a much larger part in all this than we can see so far, i seriously doubt the writers would add that extra little story on the side if it didn't mean anything. As most people have discovered, nearly every small thing on this means something much bigger.

I totally expected Janice to get shot in the last minute. Glad she didn't.
