Seeing Tails (any Tails, even if it wasn't quite the Tails she knew) jumping on someone for a hug was... a little strange. The Tails she knew didn't hug much, and he jumped on people even less. And this Tails looked so small that Cream found the whole thing rather strange.
But it was still Tails. And that made him her friend. Besides if he was smaller than she was now, maybe that meant that it was HER turn to take care of him instead. She could help.
She closed the door obediently behind her, giving it an extra push just to be sure.
It didn't really look like the kid of night for fun sleepovers... It was no less scary inside than outside. But maybe it was better, since it would be the three of them now.
She turned to Tails and smiled broadly, holding out a hand in greeting. 'Hello Tails! Do you remember me?'
