Twins do everything together: they share secret languages, they go everywhere together, and some work together. Some like Breach and Clear, two unicorn twins, hunt down and capture changelings for the government together.
Sometimes that work includes going to remote locations with not a lot of support and just each other to rely on. So this contract shouldn't be any different, right?
[This story is rated a rather high 'TEEN' for descriptions of light gore and naughty language.]
