Snaieke, looks like you got all your wishes!
And I have to disagree with paul and teitr.
Paul, i really think this is the season arc... every other season has had a similarly apparent arc, and frankly its a great idea and way to accomplish shaking everything up, both relationships and the world around them (not to mention bring back the hot redhead and stark). All this seems too complicated to just reverse on(alsion, joe, henry, and jack all have relationship changes, not to mention whatever else is differnet about time and history), but the shows done it before, so who knows.... oh i saw baltars in a print ad for eureka so i think hes here to stay, not to mention all the ads talking about how this season is shaking things up. I doubt theyd do that for two episodes.
And teitr/paul, I dont think he did it on purpose. He seems to be a very smart man, and would probably get his importance in the time hes in and causal relationships/ramifications (e.g. his town, success and the whole universe might all disappear if he went forward).
Also he could have just taken the phone if he wanted, but chose to give it back to alison.
Finally, jack is the one who left it in the coat, how was he to know it was in there when jack gave it to him, and until hed left or the dance floor was surrounded by soldiers (not to mention it probably weighs about as much as a nickel)?
Plus he was essentially a good guy the whole episode without any real "bad" in him, save the misunderstanding in the beginning... and he was first and only convert, too.
Did anyone see scenes from the next or anything? was it "this season on" or "next week on", cause if its the former we might have an answer to the reversal/two episode thing.
RE: zooey, i bet she is coming back too, as jack said in the first few minutes harvard was just getting out or some nonsense
