“I am going back Derek” Stiles whispered so no one will overhear them, even though they were standing in the treeline where no one walked by
“I assumed so when i saw the girl with the trousers standing there and you wearing your old clothes again“ Derek chuckled with a small smile that didn’t reach his eyes, the silence hung between them, eyes not meeting each other.
“Me too,” Derek interrupted, the pain is visible in his eyes “ I wish I could’ve come with you, I wish you could stay with me,” he shuddered and reached for the younger man’s hand, lips hovering over Stiles’s knuckles before he placed a soft kiss on top of them and placed them over his heart “tomorrow the Confederacy will attack and just as all the soldiers here think, i might not make it-”
“Derek you c-”
“I don’t care,” Derek finally looked up “i don’t care if it means ill give a future for you to come back to” a soft smile played on his lips though his eyes are visibility wet “If souls are really bound to find their other half i hope mine will find yours again, even if its worlds apart i hope my soul will find you again”
“It will,” Stiles wrapped his arms around the man’s neck, holding him tight “i will find you” he moved back to look into Derek’s eyes, determination visible to both of them making Derek chuckle.
“Stiles! we need to go! the portal is closing!” Lydia shouted one foot already in the glowing blue circle. Derek sucked in a breathe, pain coming back to his eyes.
“Derek,” he took the man’s face in his palms “ill find you,” he placed a soft kiss to the man’s lips “i will, no matter where you are,” he pulled back “ill find you”
“I know” Derek smiled and let go of Stiles who walked over to Lydia. with one last glance behind him stiles disappeared into the portal.
“Civil war era OR in a vortex”
he does find Derek btw. in a bakery in beacon hills. owned by the hale family and a really frowny werewolf who later becomes Stiles’s boyfriend and many years later the father of his children.
