Random question

Brought on by a book I'm reading:

Say your mother has two children by two different fathers, you and your half-brother X. (Your father is A, your half-brother's father is B.) And your half-brother's father has two children by two different mothers, X and his half-sister Y. (You and your half-brother's mother is C, your half-brother's half-sister's father is B and mother is D.) And no one was married to anyone listed. What is Y to you? I mean, biologically, nothing, I suppose. And legally, nothing either, I think. But X is brother to both you and Y. What would you call that?

Your nought-sister, presumably :)
