Bellatrix’s hands were tied behind her back, causing her face to rest in Hermione’s lush bedding that was thick with the Alpha’s scent. Was Hermione going to bring in another omega? To show her how to please Hermione properly, maybe she was upset because she felt guilty someone else would have to go through this, but mostly her omega instincts flared rejected, she was upset that there was an omega that was "better’ out there, she had gotten so used to being told she was the best omega out there and just needed to give into that nature more. A month was a long time thought, and Hermione’s rut was nearly here, Bellatrix could smell it, she couldn’t blame her for trying to find a solution.
