Katy sat on the floor of the tube station. She wasn't entirely sure how long she had been there; all she knew was that a lot of trains had been past and she hadn't got on any of them. She didn't want to leave Walford, but she didn't see how she had any other choice. Now Ronnie and Roxy had rejected her, staying would be more painful than leaving.

"Three more trains and then you're getting on the next one." She told herself under her breath. Wherever that train was going, that's where she would end up. The end of the line. She just hoped it wasn't near Newport. Katy didn't need any more memories being brought up.

"One." She said, watching a train slow to a halt at the platform. A man got off and a young woman with a buggy got on. The train set off again.

"Two." A few moments later another train stopped. No one got on or off.

"Three." Katy sighed, feeling finality settling on her. Tears started to threaten to fall again. As the train pulled off, Katy stood up and gathered her two bags. She didn't notice that she was actually crying as she stood resolutely on the platform waiting for the next train. As it came into view, Katy felt as though she was about to break down, but somehow she held it together.

"You're a Mitchell." She repeated over and over under her breath, trying to stop herself getting emotional. She had only been in Walford three days, but Katy felt like it was where she belonged. "But you can't stay." She told herself sternly.

The train stopped in front of her and Katy waited for the doors to open. There was a hiss and Katy stepped forwards. She put one foot inside the train.

"WAIT!" Katy turned and saw Whitney running towards her. Bianca, Pat and Peggy were all behind her, hurrying to catch up. "Katy!"

"I can't stay." She said, tears running down her face.

"But you don't want to go either." Whitney said. "Or you'd have left before now. You've been here almost an hour."

"I don't want to go." Katy agreed. "But I've got no choice."

"Why not?" Peggy demanded. The others had caught up. Out of the corner of her eye Katy saw the conductor coming along the platform to see what was happening.

"Because Ronnie and Roxy don't want anything to do with me and I can't stay here and deal with that. I can't do it." Katy said quickly.

"Are you getting on, or not?" The conductor said rudely. Katy looked helplessly around the faces, before she nodded.

"Bye. I'll be in touch." She said and turned, walking towards the carriage. The doors closed behind her and the warning beeps sounded. Katy sat in the seat nearest the carriage door so that she wouldn't see their faces as the train moved off. She closed her eyes and leant her head backwards, tears silently leaking from beneath her eyelids.

Suddenly there was a bang on the door and they opened again. Katy jumped and turned to see Ronnie and Roxy stood outside on the platform, both breathing heavily.

"Where do you think you're going?" Ronnie asked, raising an eyebrow.
