"What? Of course I'm a cat Thiren. Why would I lie about that, hm?" Jane can speak as earnestly as she wants in front of you, but it's still so obvious she's lying—those ears aren't a cat's. Nor is her tail.

"Do I need to meow just to convince you? You know, it's rather rude for you to be so presumptuous..." She flicks her tail in a manner imitating a feline. She seems to know you're not falling for her lie this time, but she's certainly enjoying riling you up with it.

Or perhaps she really is a cat Thiren after all? It's impossible to tell with her.
