Тімоті Лейзенбах

A young boy infected with Medusa. He appears to be around six to nine years of age, and appears to be very resilient, with even Alice commenting on his toughness. Tim calls Katherine 'auntie' and treats her as if she really is his aunt, becoming very attached to her and vice-versa, as he reminds her of her son. At the end of chapter 26 in volume 5, Tim elects to stay behind with Katherine's Medusa form in a locked room until she heals. (Source: Wikipedia)
