Deamus Headcanons :
Dean Thomas and Seamus Finnigan were both traumatized by the war : They lost friends, they killed people, they have been tortured... After helping to rebuilt Hogwarts, Dean cut contact with his friends, even Seamus, and travelled all around the world. Seamus didn't know what to do with his life and started drinking. He passed one year drinking and sleeping with strangers, mostly women because men remind him of Dean. But one day, one of this young women came to his house and told him she was pregnant. Seamus was devastated but he decided to assume the child. He started to work at the Leaky Cauldron with Hannah Abbott and bought a house. A few month later, the little Annalise "Annie" Finnigan was born. But her mother couldn't assume her daughter and run away without a word. And Seamus became a single dad at the age of 19 but he could count on Neville and Hannah who were Annie's godparents.
One day, Dean knocked at Seamus' door, to apologize for running away. And he fall absolutely in love with this adorable little blonde girl. He help Seamus with Annie the best he could, trying in the same time to reconquest Seamus' heart and trust. He finally suceed and the little Finnegan-Thomas family lived happily ever after. (And Annie became a true soccer fan, because of thanks to Dean)
