I meant to reply to this earlier, but somehow managed to forget my password. *sigh*
I think I'd really hesitate before adding completely
new storylines. I think we all want to see the story keep going forward. But some filling-in of older storylines would be fantastic. I'd especially like to see what happened with Tarik and Luscious. Last we saw of Tarik, he was a really nice guy. Then he got attacked by vamps and some strange old man said he'd like to "study" the incapacitated vampire. Ok, that's fair enough, considering said vampire was trying to kill Tarik.
Then the next thing we know, he's got Alice in the basement and is performing experiments on her. What happened in the middle?
I think some Lars/Kaitlyn ones, when they were happy, might also be good. But ... well, if I were you, I would think long and hard before doing a Valdemar/Risa one. I kind of liked the mysteriousness of Valdemar and Risa. When Risa finally exposed herself as the one pulling all the strings, it came as a bit of a surprise, in a good way.
But hey, your story, you should do whatever you think will work best.
