Well, I was trying to catch up on this thread before posting, but it moves so fast that I don't think that'll ever happen. So, I finished Trespasser the other day. I can definitely echo the people that said it affected them in real life. I finished it right before bed, couldn't go to sleep, then had to get up and go to work all depressed. And now I've been moping around for several days, going "that reminds me of Solas, and that reminds me of Solas, and that also reminds me of Solas," and getting on my family's nerves. I was even listening to the Prince of Egypt soundtrack going, I could totally apply this to the ancient elves. And while I normally lurk around on here and don't speak, I needed to come to people who would understand that it's real for me and totally not lame to get attached to fictional characters.
I really loved the DLC. The first couple conversations with Josie and Varric had me laughing out loud, Iron Bull and Blackwall were my bros like always, and even Sera who I'm normally fairly ambivalent about, I couldn't help but love her, especially since she was one of the few who said anything about my relationship with Solas. (Others did, but more in the "have you heard from him?" way than in the "sorry he broke your heart" way). I had a very emotional response to Dorian telling me that he was leaving me. My heart dropped into my stomach. And then I ugly cried when he gave me that crystal. BFFs forever. And then Solas showed up, and my inquisitor turned from badass world leader to lovesick puppy. When they said he sent that injured qunari through, my Lavellan (and I) was like, "He still loves me!!" And even when he was telling her he was going to destroy the world, she was still going, "Yeah, destroy something something, whatever, baby. TAKE ME WITH YOU!!" Not entirely thinking that one through... And god did it hurt when he left. AGAIN. 
Well, my Inquisitor did not disband the Inquisition. It's probably the better option to disband, and deep down she knows that. But now that Solas is gone and Dorian is gone and Varric is gone and Cass is Divine and everyone has left her, that's all she's got. Her clan's alive, but she was never really close to them. She was a weird, unpopular kid, and the Inquisition's the first time she's really felt like she belonged somewhere. She keeps it together for selfish reasons masked by good intentions. I foresee her becoming obsessed in the pursuit of Solas. She tries not to sleep because she doesn't want to be haunted by him, not until she can effect a change on his state of mind. As far as her arm, my Lavellan is only human (well, elf, but you know what I mean), and pride is a big flaw of hers. It'll take a long time to learn to live without the arm. It's something that she won't even want to look at, and it'll be a struggle to heal herself emotionally. (My cousin asked me if she'd have an arm in the Fade when Solas is watching her, so it made me start thinking about her adjustment to that).
This is doubtful, but I think it'd be cool if we could recruit our own elves to our cause and have an elven civil war of sorts. Even if the world is pretty awful as an elf, I'm sure a good chunk of them would rather try to fix this world than have it destroyed. My Lavellan wouldn't keep what she'd learned secret, and she'd use that to recruit away from Solas. She'd hate doing it, but the only way to beat him is to use his own tools against him. Also, everyone who isn't an elf. The whole "tear down the veil" thing probably won't fly with them.
Although if he asked me to come with, I'd probably drop it all and go... 
Ok, that's enough. Back to lurking. *Channeling Cole* Now forget...
