RWBY Lap Dog

I hate them,
They Betrayed me,
I wanna kill them,
Make them pay for what they have done.

Lupin's only goal is to react his revenge against Ozpin. Or at least that's what he tells himself sitting in his white walled prison cell.
But what happens when Ozpin comes to him with an offer, that Lupin can't seem to refuse? To make things even worse, what if another team of Huntresses befriend him? Will Lupin's revenge see light, or will he realize that revenge isn't the only thing he's after.

I do not own RWBY that right belongs to Rooster Teeth, so please don't sue me.
