Bella wears her indigo dress and her indigo heels with their straps that go all the way up her calves, and she nukes Sherlock some breakfast, and she waits.
"Hi, Jarvis," says Bella. "This is Minnie. I wonder if you'll be able to hear her through the phone? Minnie, you want to say hi?"
Bella smiles. "My phone's not particularly fancy, but some people nowadays have phones that cross with books a little bit almost like the machines that go on the internet," she says to Minnie.
"You seem like a nice person. I really don't understand why you'd kill people, even if you've been stuck in a really annoying situation for a very long time," Bella says to Minnie.
"I'm sorry," says Bella.
"My other friend found David's obituary," Bella says quietly. "He died on November fifth. 1933."

"A vampire got him," Bella adds. Normally she wouldn't tell anyone this, but Minnie is already herself a ghost. [Any evidence he turned?]
