Jones is widely traveled.

Two thoughts have occurred to me. First, I imagine in every long relationship Jones has with someone, at some point they notice she isn't aging, is very heavy, has superhuman strength and invulnerability, and ask Annie's question: "What ARE you?" In the past, I suspect Jones would either tell them if she felt she could trust them, or she'd disappear from their lives and start over again somewhere else. Since she's a member of the court, now, I doubt that's operative anymore. At least for the moment.

And second, I wonder what Jones did when she was running the Landon estate. What would a good hearted, extremely intelligent, VERY experienced immortal being do with lots of money? Buy books, yes. Possibly work to help people. But I wonder if we might be looking at one of the early financial backers of the Court...
