Work Text:
Christofer cannot pinpoint the moment he found himself attracted to Kate Lethbridge-Stewart, maybe he always had been. He wouldn't be the first and wouldn't be the last under her command to find her beautiful. He can't pinpoint when he fell in love with her, but Christofer knows when he became aware that's what he felt.
It's when he is watching her spinning into a wall, and he wishes the bullets worked against the toymaker. Killing has always been an essential part of his job, but he has never ached to kill. But at that moment he did. He wanted to kill to protect her, not kill because he had to protect her.
He's never felt that level of love before and it terrifies him.
