 It is mentioned several times that Patrick would like to have children. After Pippa miscarries and Patrick is, so he claims, rendered infertile by a freak accident (for which he unfairly blames Victor), he adopts a dachshund called Denzil, which Pippa describes as his "baby substitute". Denzil frequently appears with Patrick through series 3-5. Despite their animosity towards each other, Victor ends up saving Patrick's life in "The Wisdom of the Witch".
