Wow, now I'm really confused.
Yeah I'm confused too. That's why I posted at the beginning of this thread, Lindsey's reappearance appears at first glance to be a resolution, but really it creates more questions than it answers.
Myself though, I get a kick out of trying to make sense of the unknowable, so it's a good confusion.
For what they're worth here's some of my thoughts on your thoughts.
Someone posted that Gunn may join Lindsey and Eve - i think this is very likely.
I confess I hadn't considered that until Sehkmet posted it. I had only considered Gunn turning to W&H. The way you describe it, it sounds interesting. You two have sold me. I'm hoping for that now too.
When Gunn is choking Eve, and he says she has to breathe therefore must be human, how do we know she wasn't faking it? She seems to have been faking afterwards when she acts all weepy with Fred. Maybe she's not human, and she was just trying to get sympathy out of Fred and co. to get them to like her and be less suspicious of her.
Now that I had considered. However...
Some possibilities create credibility for themselves by the very fact they exist in the story.
Having Gunn notice the fact Eve breaths is not really necessary to the present story. It's only purpose would be to convince the viewer Eve is human.
If the writers were to say at a later date Eve is not human, it makes Gunn's statement here nothing more than a non sequitor, red herring. To do this detracts credibility from the story. If they do it too much nothing really means anything, except the denouement, and that sucks.
Not that the writers wouldn't do it. They did it all over the place in Buffy Season 7. We still don't know why Annabelle ran from the Summer's house.
Angel season 5 is different though. Joss Whedon isn't distracted by the entire production of Firefly and Buffy this season. I'm hoping he's directing his personal attention to, and guiding the story of Angel Season 5.
My opinion based on previous Joss-guided season's of Buffy is Joss will spin the story in an unexpected direction, but he won't do it cheap. Eve might turn out to be something completely unexpected, but whatever she is, she'll breath. That's my prediction.
I think that Lindsey's plan is to bring down Wolfram & Hart. We know he tried to help Angel destroy them back in season 2, and to discover that Angel is now running W&H would make him very angry. So he wants to bring down W&H and Angel.
That would seem to be the most logical conclusion. You know what bothers me though? is the traditional bout of writer insanity that seems to strike Angel writers after the first season break. In Season 3 Holtz had stolen the baby, and we were all thinking Angel would have to go to the hell dimension to retrieve his child. It was the obvious conclusion, and what a story that would have been. What happened? Connor came back as a teenager.
STUPID
Last season Connor Boffed Cordelia just before the break, and we're thinking this is crazy. They have to make sense of this after the break. What happened? They didn't make sense of it. They turned it into some kind of twisted romance.
I'm hoping they don't do the same thing here and go off in some kind of insane direction with Lindsey.
Again though...Joss is here this time. Hopefully Joss will protect us from writer insanity.
The events on Conviction take place about a week after Chosen.
I didn't know that. Traditionally things happen in real time. What did I miss? Does this mean things in Angel this season are actually supposed to be happening months ago?
That also raises the question of if they got Angel to use the amulet in the first place. We don't know if Eve was employed by W&H while the events of Home took place. Maybe the Senior Partners had another plan for the amulet.
Plus it was Lilah who gave Angel the Amulet. To organize Angel getting the Amulet they would also have to have hoodwinked, or corrrupted Lilah. I expect a return of Lilah. Don't you?
Here's another possibility. Have you noticed how Eve keeps mentioning she attended Santa Cruz university. Is it possible she met Lindsey there?
