Hey [@Megarandom]:

Unless you already have something planned for the aunt killed by Demon thing it might make a good story dynamic to have it so Lilith was one of the demons that tore apart his area of town and killed his aunt before departing Veiron. If you don't like it it's fine I just thought it might make a really good point of conflict since he's kept from his revenge by the fact that Susanna is in control and Lilith would be tempting Susanna to kill Urisk.
