I love Arthur. No matter his personal feelings, he always lets his children make up their own minds (whether they're biological or 'adopted'). He'll always be there for Harry, but if Harry wants to stay with Severus, who is he to stop that from happening? Now it's Severus that needs to step up and become 'dad'. I'm just so glad that innocents were not punished here.
Thank you so much. :D I'm glad that you liked Arthur. I really did have a lot of fun writing Arthur.
Thank you again.
