In this comic, The old house that they buy represents the old house archetype. The Hero is represented as the father who comes and saves the mother who was almost killed by their adopted daughter. The "typical" plot pattern is a couple buys a new house with their new child and then that child turns out to be evil and tries to kill them. Like in, "Orphan" or "The Omen".
This house is beautiful! I'm so glad to have bought it. Thank you!
you're so welcome! It's quite old but it has character!
