Like lightning, River Song flashed before her by way of her vortex manipulator. The sight was all the more shocking as River arrived in nothing but a creme colored satin and lace teddy that was all too short, her wild mess of curls in disarray. The original intention of her call was evident. But this was a younger River than the one Clara had met before. She was more vibrant, more passionate and, obviously, more alive. For River, she was still fairly a newly wed.
The Doctor was off inspecting the Tardis and desperately searching for a manual. River took one look at Clara and smiled without shame. "You must be new. I do love new things."
"I'm Clara," she reached out cautiously at first, still confused by River's existence.
"Doctor River Song," she beamed as she shook her hand. "I'm the Doctor's wife."
"I know," Clara whispered under her breath. She spoke up. "We've met before."
"We have? Well then, I look forward to that. I'll make a note of it to remember." Another crash. The Doctor yelled. "Right then. You need a pilot. My husband needs an assistant. Could you check on him for me, dear? I'll set us right on course."
"Right then," Clara wandered off to find the Doctor but watched in amazement as River took command of the ship. Taking hold of the controls, River stabilized the Tardis, then caressed the console, whispering, "Good girl, there we go."
"Doctor?" Clara approached slowly. "There's someone here to see you." He stood up and turned to follow her.
"Someone here?" His curiosity was quickly replaced with a flood of emotions at the sight of his wife's backside. He was petrified and could feel his tongue swell and his palms grow clammy. Clara watched in silence. River felt their presence behind her and turned to face them. The most endearing smile overwhelmed her face as she looked into his eyes.
"Look at that. Everything changes." She sauntered over to him, still paralyzed and unaware of what exactly he was feeling. He was overcome with emotion, that much was certain. But which one dominated over the others was yet to be determined. She touched his face tenderly. "Oh, but I love it. You're all sort of… mature."
