Blaise was currently combing through every crumb of the miserable son of a bitch’s life to figure out why exactly Snape had gone to work for Theo’s biological father. It currently appeared that Snape had been working with him for years since before the Lestrange and Nott families split in the seventies. Theo was a bit peeved and might kill someone about it later. He hadn’t actually decided exactly who was to blame, but once he figured out whether there was anyone who had known and neglected to mention it, he would make sure that they wished that they hadn't been born.
