I was annoyed as I was watching that he didn't just tell her what was happening, but I mulled it over while walking my dogs after viewing, and decided that Cole didn't tell her because he KNEW she'd be like "To hell with our happy life, we must fight the time war!" before pouring the red tea into him with a funnel if necessary, and he just didn't want to actually SEE how willing she would have been to undo their happy memories. I do wonder, though - if Cole had just played "chicken" with the red forest in 1959, would it have ultimately resolved itself when the Witness was stuck on the farm with his loving folks instead of heading to the future with him mom...
And is Cassie still heading to whatever year to die and leave Cole the message - 2020 or whenever it is - and if she DOES that, wouldn't it seem that she IS in league with the Witness at that point, because it is that message that will set about the whole chain of events that leaves to conception of the Witness, and at the time it is left, presumably Cassie knows enough about what's going on to forestall it by just NOT leaving a message?
It just makes my brain hurt when I think about it too hard.
Anyhow, I don't post much here but have enjoyed reading everyone's comments this season -- 12 Monkeys is definitely one of my favorite shows, and I thought this was a great cap to the season, and I'm dreading the long wait til season 3. And I'm just TICKLED that Jones got a dog. I am, as always, way happier about the addition of a dog to this (or any) show than I am about the addition of a magic baby.
