Dream and Nightmare are siblings doesn’t matter if he’s corrupted or not they are still siblings if someone changed ikr doesn’t make them no longer related so doesn’t mean corrupted Nightmare is no longer related to Dream.. even the creator or DreamTale says they are still related (even tho they still say it’s fine to ship them even tho they are siblings) so you people need to stop saying that corrupted nightmare is no longer dreams brother just cause he’s corrupted Omg (I kinda vented a bit but it’s also true plz don’t hate me)
Nice but in canon Nightmare will win, cuz the creator said he really good at playing violin and If the apple accident didn't happen, he would be an amazing violinist in the future (and Dream is.. well idk tho i heard he would be an lawyer)
