In this AU Nightmare and Shattered are brothers. Shattered is 24 and Nightmare is 21.

~Short backstory~

One day Shattered went missing (Nightmare was 15 and Shattered 18). He came back after 4 years (Nightmare was 19 and Shattered 22). Nightmare was really mad at Shattered so he didn't let Shattered in the house for 2 months. Later he gave up and let him in. Shattered refused to tell Nightmare anything what happend. (The same text is in one of my wattpad stories so don't tell me I stole it from someone)
