Oh I'm totally with you on the emotions thing. After all, isn't emotion the root of action? Why else would Cas have chosen to go rogue, if not for his feelings (however they may be interpreted) for Dean? And definitely yes on the Cas slowly becoming human thing. The way I see it, angels feel emotions but on a plane much different than humans do... idk if that makes sense at all, and who knows if that's even remotely close to what the writers were going for, but yeah. *hands*

My beef with the angels WRT emotions starts when people start trying to use that as a basis for making Cas/Anna canon. I'm completely okay with angels showing emotion (Zach has certainly shown some, as did Uriel, Gabriel, and even Cas), but when it's used for such lame purposes as just another boring, heteronormative romance subplot - "Oh, Cas is fallen now, he's able to feel love and realize his ~true feelings~ for HIS FUCKING SISTER Anna! And oh, Anna knows what it's like to have human emotion, so they're so perfect!!!!1" - I'd rather be gagged, weighted, and tossed into the Ganges.

if they paired them up and completely glossed over the incest factor or came up with some bullshit "oh they're an exception and this is why" hand-wave.

What's terrifying is that I can honestly see them taking either of these routes, especially since Misha has stated several times that he'd really like to see some sort of romantic interest pop up for Cas at some point. UGHHH, STFU MISHA. I LOVE YOU BUT SERIOUSLY, NO, STOP IT, YOU ARE HURTING ME. DNFW.

A platonic brother-sister dynamic would be very cool, or even a commandant/subordinate soldier thing (though that would be harder to pull off since Cas is basically working solo now - he's not under anyone's command but his own.) I would love for that "history" they mentioned to be a platonic thing that related somehow to Anna's previous position in the hierarchy and her choice of falling/how it affected those she was in command of at the time. That would be so much more interesting than "oh hey btw they used to be ~in love~, even though they're noncorporeal, genderless siblings."

I liked the idea of Anna too, but imho her story should have ended when she was re-angeled in the barn. Like you, I like the idea of her, but it's the execution that I have a problem with. Nothing against Julie McNiven or anything, but she's just... dull, and seems kind of extraneous to me. If they had her play a bigger role in the apocalypse as a badass warrior angel instead of a love interest for Dean (and now, possibly Cas D:), I'd love to see her around more. But, well. Yeah.

In conclusion, I'm just gonna go back over here in my happy corner and eat candy and dream about OTP!porn. \o/

OMG I TEXTWALLED YOU, I'M SO SORRY. :$
