Trisha did come very close to falling over--the girl was much heavier than she appeared. And completely naked, too. Trisha was pretty certain wherever the girl was from, it was a very different place than she was.
She did spot the bandages, though. Was she hurt?
"Hello, dear," Trisha said, smiling and patting her on the head. "What's your name?"
Maybe speaking to her in person would get better results.
