Time to catch up on what I've missed! First of all, thanks to whoever answered my question about the multiplayer character customization. It's really strange that they decided to have color changes unlock later, maybe, if you're lucky, and not just give the option to everyone in the creation screen. I hope they'll change this for the actual game.
And as for my thoughts about Thane's illness/possible fate of his character in ME3: I didn't mind that Thane started off with an illness. It seems realistic to me that there are just some people who have one terrible thing after another happen to them, and while it's not my favorite part of his character (that award goes to the assassin part), I don't dislike it. I would really like to see him cured, but if not... I've accepted it. I mean, he gives us all fair warning by telling Shepard that he's dying when they first met, which is more than I'm used to getting when my favorite characters die (and this happens
a lot, more often than not).
Of course, I hate to see my favorite characters killed off, but depending on how it's done, the scene could range from "a powerful, emotional moment" like Saren's suicide to "Why would you even do that? There was no reason for it!" to anything in between. If Thane does die in a powerful way that makes sense for his character, and my Shepards are allowed to have a reaction that is for their character, then I'll be all right with it. If not, then I'll express my disapproval by telling the forums what I would have done differently.

But I don't think that'll happen, because I've been mostly happy with the spoilers so far.

Oh, I see, well you're lucky you got the "I still haven't forgotten what we talked about" line, that does work really well!
After the suicide mission when he said "blowing off steam" to my Shep she was like "I thought it meant more than that to you, Garrus, shame on you! ...but I'm happy to keep blowing off steam.." 
No worries, your Shep will know how much she means to Garrus come ME3.

It's too bad about the messed-up dialougue after the suicide mission though. I think most people got the same line as you did.
