Rose stood up, thoroughly creeped out by her chips. "I ate that??"
She backed away from the table, knocking chairs over in the process, almost tripping several times until she found a wall at her back and relaxed. Then, remembering what these walls could do, she flinched and jumped away from it, just as something reached out and pulled her into the wall..Rose fainted.

When she came to, she was in some sort of..corridor, with the same swirling walls, but at a different intensity, which made her realise instantly that she must be inside the wall somehow. She tried pushing against the wall, but it was solid and, well, like a wall. She shrugged and started walking.
