Aderyn paced around the console room. Once again the Doctor had locked himself away in his room. But Aderyn needed company. She didn't trust herself to be alone for too long. She threw open the TARDIS door and sat on the floor, her feet dangling in the air. She had no idea where the Doctor had brought them. She didn't particularly care either. All she cared about was getting to someone who would be able to provide some relief from the pain she was feeling. She watched people walking along the streets below and the gentle snow fall. A cool breeze wafted around her legs, making her shiver. She knew who she would go to. She would find River. The TARDIS would know where to find her. She wouldn't be in Stormcage anymore. As far as the world was concerned the Doctor didn't exist so there was no one for River to have been jailed for murdering. She stood and dragged her feet to the console. She had just been about to move the TARDIS when she realised she couldn't do it. River was, whether she used the name or not, a Pond. She was their daughter. Would Aderyn really be able to look her in the face without thinking of them? No, she knew she wouldn't be able to do that. As much as she loved River, she knew she couldn't cope with seeing her just yet. She realised that she had no one left. The Ponds were gone, she couldn't see River and the Doctor had become a hermit.
She decided that maybe an excursion would help take her mind off things. She pulled on her coat and checked to see where they were. Her hearts thumped loudly when she looked at the scanner and saw the readout. London, 1890. Perfect. She knew just where to go. Even if it was just a brief visit, she would be glad to see a friendly face again.

The day was cold and the snow crunched pleasantly underfoot as she walked. They had been in the same place for at least a week and she had mentally cursed herself for not checking sooner where the Doctor had brought them. She knew her happiness would be short lived. Happiness always was these days. But she would take any break in the saddness where ever she could find it. And she knew she would find it at 13 Paternoster Row. The bitter air had made her hands cold, causing her knuckles to sting when she knocked on the door. Strax pulled open the door and was surprised to see her. It wasn't like her to turn up unannounced. She told Strax she would like to see Jenny and he led her to the library.
A fire was blazing happily in the grate and her hands and feet were soon warm again. She sat herself in a corner near the fireplace when a voice from the doorway made her jump "You can sit on a chair." She looked up to see Madame Vastra enter the room.
Aderyn shrugged "I like sitting here. It's comfortable." Vastra sat on a chair opposite Aderyn and regarded her with a frown. Not a word was spoken between them until Jenny entered carrying a tray of tea.
"Strax said the Doctor's lad was here," She said cheerfully. But her smile vanished when Aderyn failed to respond with her normal devious smile and battery of sarcastic quips. "What's wrong? Where's the Doctor?" Jenny quickly put the tray down and knelt in front of Aderyn.
Aderyn hadn't allowed herself to cry over the Ponds since the day they departed. She had allowed herself a few tears but nothing more. But now she couldn't stop them. Tears streamed silently down her cheeks as she looked up at Jenny's concerned face.
"The Doctor is in the TARDIS," she said quietly "and the Ponds are gone." Through her sobs she managed to tell them everything. She told them about the trip to New York and the picnic in the park. She told them about the book and going to find River. She told them about the Weeping Angels and about Rory and Amy's jump from the roof. When she got to the part about Amy's goodbye, it was several minutes before she was able to talk again. As she sat on the floor sobbing uncontrollably, Madame Vastra pulled her to her feet and sat her on a sofa. Jenny poured tea, forced a cup into Aderyn's hands and threw an arm around her shoulder. When Aderyn was finally in control enough to form an audible sentence, she told them of the past few, awkward days in the TARDIS with the Doctor.
"Where is the TARDIS?" Vastra asked calmly.
"It's hidden. The park around the corner by the tree. There's a ladder." Aderyn stuttered. She expected Madame Vastra to leave to find the Doctor, but she didn't. Instead Vastra poured a fresh cup of tea and called for Strax to prepare a room for Aderyn.
The Doctor was alerted as to Aderyn's whereabouts and was told that he was welcome to join them. But he kept to himself. And so Paternoster Row became home to Aderyn.
