Yes, Peter always trust that Olivia and Astrid will look out for him and keep him safe, which, I don't know if you saw last night's ep yet or not, may come back to bite him in the ass. I find it awesome that they made this deliberate choice with both the character and the series. I can't wait to see where they go with it.
As an aside, do you think you'll be watching Supernatural next year? I keep going back and forth with it. I love Jensen and Jared and I'd watch for them but I keep coming back to it being a five year series and I just don't know how I feel about a sixth year, I'm having horrible X-Files flashbacks where it just went on, and on, and ON when it should have just stopped.
At the same time I can see so many storylines with Samifer back and stalking/protecting Dean that I just don't KNOW!
