(Stiles POV)
"Can you tell him?" Eli cried on my bloody chest "tell me about him. Say can you tell me about him" I corrected and he whimpered "can you tell m-me about him..." he said and I smiled. Clementine ran over "dad?" She gasped looking at me. Bloody. Broken. Dying. "Hi princess." I chuckled, blood spilling from my mouth "what the hell happened." She asked kneeling over me. she looked at the stab wounds all over my body. "Dad... oh my god... HELP!!" She screamed "no Clem...." I said "I'm ready princess." She sat down next to her brother. "So this is it?" She asked and I giggled "dad..." Eli whimpered. I looked down at him. "Yes baby?" I answered. "Tell us the story." I smiled at him. "Okay. Get comfy." Clem laid on my legs crying and Eli cuddled up on my shoulder. "Okay.... Your old man was born November 7th, 1988. He was born to Tallia hale and Alexander lee. His father was a human like me. So when his mom got pregnant he couldn't be in daddy's life."
(Not exactly sterek. But it does imply that Derek and stiles we're together before Derek died and now stiles is raising his kids.)
