Wow! I was so relieved to see that Clark hadn't been called by Angelica, but that he had just flown off to the hospital to help. And it was exhilarating, though also horrifying, to see Lois and the slayers go after him to the hospital and take up the fight against the vampires themselves among the carnage there.
I absolutely loved how you wrote the scene between Lois and Clark:
There was pain in Clark's eyes, pain that hadn't been there before.
“Why would they do this?” he asked. “If it was just about food, I could understand, but…”
He didn't really understand evil. For all that he'd traveled the world, there was part of him that had kept its innocence.
It was one of the things she loved about him.
Like Lois, I totally and completely love Clark when I read this.
“Lois…” Clark said. “I…”
There was a look in his eye that Lois hadn't seen before, something she hadn't expected.
“I was afraid I was going to lose you.” He sighed. “I don't know how it happened, but you've…”
Lois kissed him.
Kissing, in Lois's experience had always been a pleasant prelude to other things. It was something that she considered herself reasonably good at, but it wasn't something she thought much about.
This kiss was something different. It was as though something clicked inside her, and suddenly the world slipped into focus.
This was the man she was going to spend the rest of her life with.
He was the sort of man she'd always dreamed about, the good man who wasn't afraid to be strong. He was the first person she'd ever known who was not only willing to put up with her, but who could more than keep up.
He was handsome and brave and wasn't afraid to sacrifice himself for the common good. In a way, he'd sacrificed himself already for her.
Sorry about the long quote, but this is altogether wonderful.
And then Clark's eyes become glassy, and he is unaware of her. He has been called by Angelica, hasn't he?
Shayne, you must make him choose between Angelica and Lois. And no matter what he has promised Angelica, he must choose Lois. He has given Angelica his word? So he must protect the demon and give her the means to kill thousands and thousands of people, if she so desires? Clark, there is such a thing as taking the honor of keeping your word too far. Remember that.
