Big Changes!

I'm really scared and nervous right now... I think there are some big changes headed my way, and I don't know what to think about it all.

My human has a really good friend that she met when she was in art school, Kendall. She doesn't see her very often, because Kendall moved to Tulsa right after graduation, but they talk on the phone and email a lot. Kendall has a daughter named Denise who is my age, but I've never met her.

Anyway, a couple of nights ago, the human got a phone call from the Tulsa police station, and they told her that there had been a fire at her Kendall's house.
The fire was too bad for the firefighters to get into the house, and Kendall... didn't make it.
The human has been so upset about it all, and I can't blame her. I don't know what I'd do if something happened to Ivy or Avalanche.

But here's where the changes come in: Denise has a dog named Jip, and he was sleeping in the room with her. Apparently, he smelled the smoke and started barking, so she woke up. She threw her desk chair through a window and she and Jip climbed out that way because the smoke was too thick to leave any other way.
Denise doesn't have any family but an elderly aunt in North Carolina, and the human said that Kendall had gotten a will drawn up only a few months ago and wanted Denise to come live with us if something ever happened to her. The human left yesterday to go get her and help Kendall's friends in Tulsa arrange a memorial service.

Denise lost everything in the fire except Jip, and I don't really know what to say to her. I want to help her and be her friend when she gets here, but I don't totally know how.
The human mentioned a long time ago that Denise likes American Girl dolls like I do, so I decided to give her my new Marie-Grace.
Only now I feel really silly because she lost her mom and her whole life, and all I can think to do is give her a doll? But I don't know what else I can do.

Has anyone else been in this situation? I want to ask the human for advice, but she isn't here.
