[Isabel, Grand Central Terminal, Gift Shop]

For better or for worse, and for reasons that Isabel herself couldn't tell, she had followed the boy with spaghetti right into the gift shop. It had seemed... remarkably simple and free of electronic advertisements, or even devices on which they would be displayed. None of the usual corps had their advertisements here either, meaning this was a pretty strange place. Especially for a store. 

She didn't have her stealth gear on, but she was still taking measures to keep herself hidden - or at least, make herself not obvious. It was from this position that she watched Frisk take the toy train, and her eyes narrowed as he stood still for a second, wondering what was happening. As he picked up the train and left, she followed him out, only stopping any attempt at hiding herself when she saw that the outside was quite different. 

"...Hey kid..." she finally spoke as she revealed herself to him, wondering if she was being assaulted by a mage casting illusions on her at the moment and ready to be shot right in the back at any moment, "What did you do? Did you do something?"
