Murdoc

 Murdoc is Tove's oldest son, although he isn't related to her at all. Murdoc and his siblings, Lochlan and Saoirse were taken in by Lorcan, Tove's mate. Lorcan is their uncle technically, and he sympathized with his sister, and in a moment of sincere generosity he decided to do his sister a favor and take in her pups, something rare for wolves to do. Murdoc doesn't like talking about his scarred face to anyone, except for Tamsin or Tove. Murdoc feels extremely guilty for Lorcan and his sister Deirdre's death, and feels he's responsible since he "failed to protect them." This is both Tamsin and Murdc's shared burden, and have become closer because of it.
