"Skye?" He reached out and Skye reached out and grasped his wrinkly hand.
"Hey there big guy," she smoothed his forehead, her thumb caressing each wrinkle. "I'm always here for you." Placing her forehead against his, she slanted her lips over his, cupping his cheeks with her hand. A slow and salty kiss as she pulled away, tears spilling down onto her cheeks.
"I love you Skye." He smiled, barely able to see from the cataract but his senses were still good as with his rough estimation, it felt like he was staring at her. His fingers threaded through her hands, bringing it up to kiss it. "I didn't think it was possible, but I wanted you to know that I never regretted it for one moment." Logan laid her palm on his face, her palm getting wet from his own tears. "Growing old with you… was the best adventure of my life."
He pulled her close and kissed her, his lips mapping hers. He grunted, gasping. Skye knew he was hurting, hurting so much and letting him go was the best way. Logan, the Wolverine, the man who couldn't die was dying of cancer and his body finally aging to something similar to a eighty year old, he couldn't undergo any other treatments. He held on for so long, saying he wanted her to go first so that she need not be long when he was gone, but Skye couldn't bear to see him in anymore pain.
She looked up, watching Helen's daughter inject the medication into his drip. An easy death. He wasn't dying in battle as he thought he would from all the years of fighting as an Avenger. He would fall asleep painlessly.
"I love you Logan." Skye whispered, savouring the feeling of his hands weaving into her white hair. "Thank you for being there for me." His hand trailed down her chin, fingers stroking her skin as it made its way down to her hand, pausing to play with the gold band on her finger. He pressed his soulmark over hers on the wrist.
Love surged through her, so much love that even words couldn't describe.
She took a shuddering breath, laying her head on his shoulder, feeling him drift slowly away. Her daughter lay on the other side, quietly crying. She kissed her father's cheek, murmuring, "Good bye papa."
And then he was gone.
A/n: The idea was that Logan started to age after he finally found his soulmate. So yes Skye is also old.
