"Hey!" Annie calls, hanging out of her dressing-room door. "Heard we had a visitor. Do you want a tour?"
"Don't you have work to do, Annie?" Chris asks as he walks by.
Annie gives you a sheepish grin. "I do have work to do. But I can at least give you a tour of my dressing room, right?"
You enter the room. Maybe, by looking around, you can get an idea of who Annie is.
I've also posted a couple of short works of fanfiction about Annie to AO3. Cast and Crew (1,800 words), set immediately after The Play That Goes Wrong, is about Annie's early days as an actor in the drama society. The Annie Twilloil School of Problem-Solving (1,300 words), meanwhile, is about Annie and Robert trying to reunite Jonathan with his daughter.
