D: (You just said River, not a pairing so let’s go with this)
River carefully turned the key in the last lock and slowly eased the door open. If all of her sources were correct, she should find what she was looking for just beyond this door…
Jack Harkness was not what she was looking for, but here he was, holding the ruby she’d actually come for.
“Jack!” she hissed. “What are you doing here?”
He gave her that trademark grin. “I need your help, and I knew I could find you.”
River rolled her eyes at him. He tossed her the gem. “You in?” he asked.
She pocketed it and smiled back. “Always.”
