There's something happening here...
OK, so up until about a week ago, Nina was listed as being in Ep 16/the series finale. Trevino was in several eps and Steven was back for at least one. Fast forward to when I checked 2 days ago, both Nina's IMDB and here:
While before, Nina's said she was in TVD from '09 to 2017, the other day, it just said til 2016 (her voice over at the end of 7). Then I came here and she was no longer listed with the cast for the finale. Steven was also no longer listed anywhere and Trevino is down to one ep. TODAY, season 8 episodes are no longer even on here(!!!)
Thoughts: only the first 3 eps of 8 had titles. As of 2 days ago, they also had bigger cast listings than the unnamed eps. A week ago, there were much more characters listed in the remaining 13, counting all the new folks. I'm thinking that they decided to strip things down until each ep is titled and at least in preproduction. But, that doesn't mean that Steven didn't drop out and Trevino didn't decide not to shoot as many when both actors were recently asked to reconfirm. Which btw, would be INCREDIBLY lame of both, as they most definitely have the availability..particularly with JP and KW so willing to work around the schedules of everyone they most want back.
As for Nina, it's not looking good. If she had just been agreeable and done what she ABSOLUTELY owes to EVERYONE, for SO many reasons, it would have been publicly confirmed all over the press by now. You might not think rating matter much anymore, but they do! It's extremely important to keep viewership up and to keep the network happy/advertisers invested because the fate of TO hangs in the balance. It went from the death slot to not even getting a co-airing/the same season. It's gone til '17 and that's horrific news. It gives fickle viewers too much time detach from it, it complicated things for the cast--who has already shriveled to an all-time low, it means no last cross-overs and it means that Should It Not Make It Past 4, we will NEVER see any of the Mystic Falls crew again. The ONLY possible light at the end of that tunnel is that there is the potential for it to work out in great favor if in-fact anyone from TVD is ready to make the move. While it seems that TO is actually filming now, maybe not the entire season. If there are still working when TVD wraps, anyone going down South to NOLA will be able to go shoot, as opposed to any double-duty.
But where Nina is concerned, I really do think that the Nianers and some Dobrevics finally managed to blow it for everyone. Their relentless hate toward Nikki (and bullying of Julie) is what caused Ian to start going off like a jerk in extremely public forums. It's been extremely clear for a LONG time now that despite what Nina used to say, that friendship remainded anything *but* strong. The stans drove a permanent wedge between the two. I don't think Nina felt as strongly against him as he her, because she wasn't the one being attacked or harassed 24/7. She walked off her show, put 200+ jobs in jeapordy, acted like her career mattered more than the rest of the cast/made a selfish choice, and STILL managed to come out smelling like roses. Hell, her super fans are SO supportive that they went bananas over a damn ten second voice over. And pretty much EVERYONE has been willing to happily accept her return for one measly ep (to tie up Elena's ENTIRE storyline).
So for her to STILL refuse that, after all the public and private support she received from Julie, of all people, And the network And the cast, she's either waaaaay more selfish than anyone thought (and no longer worried about keeping TVD fans when she's gotten on the track she wanted to be on for her film career), including rubbing elbows/befriending ALL of Hollywood, or.... I dunno if there is an "or." Not if she's not returning. Julie and Alec will work around ANYTHING for her. It's less than 2 weeks of her time. I GET that Ian's public humiliation of her SUCKS. But, she doesn't *have* to shoot any Delena. They can come up with countless ways to get around that.
I don't think killing Damon before waking her is the best laid plan (unless her memories of him are going to be wiped, which is a bad idea and I PRAY they at least won't won't her of everyone/everything), because she's already mourned him once and he's the face she will most want to see upon waking. Further, Ian would have to be EXTREMELY sure he's done for good, and his career isn't in good enough shape
to decide now that any possible "TOing" is out of the question. But hell, they can still figure something out. Despite what the Delena crowd believes, they are MILLIONS of fans that care about more than the Delena Diaries. And everyone misses her SO MUCH, we'd all be happy with any number of solid wrap-up's for Elena's storyline. Not to mention the chance to see her reunite with everyone else. And then of course, there is the possibility of a future with Stefan. Maybe not right away, she doesn't deserve that and he deserves better/is with Caroline anyway, but if we time jump into the future.... Hell, he's the only other vampire who doesn't want to be one and who really wants a family. And she's still The Cure.... #justsayin
As far as NINA goes: while everything is still subject to change, especially if she'd only formerly agreed to the finale, it's not looking good.
