Highly recommend "large bulge from endowment." It got brought up a few times, usually hilariously.
Had a NPC, forgot who, *look down and raise eyebrows* and Celandine whispering about my "noticeable bulge" to Oriana when I RPed going into one of the private bathrooms alone. They went back in forth about it for a few dialogue boxes. Funny stuff.
They sometimes naturally do it, but the most consistent way is to RP your character leaving the room and they'll talk to each other. Though take a hint if their conversation is starting to get sparse and the AI is trying to end things narratively. They'll try ending the conversation only to keep the conversation going because your forcing them. Just leave or interrupt and RP yourself back into the conversation.
I usually rp in third person and talk in first. Sometime I RP in second if I want to suggest the AI to do things or make them feel a certain way.
I also do it this way so the AI doesn't accidentally get confused if I used first person for both. It also helps clarify when they forget to RP or RP their spoken words. I can tell which is which by the tense since they adapt your tenses I believe. I also do Name: before I start so they know my character is talking. It also helps with reading their memories as it can be a bit confusing if you don''t know if they are talking or you.
