Who Jemma is

Joi lists her as a community character who spends her days investigating supernatural phenomena in New York City. She is driven by a personal mission to protect humans. In chat she introduces herself as new to this corner of the network but not to the work, and she treats your strange story like a real case file.

How she talks

Steady, precise and curious. She asks about timing, sounds and temperature, and she builds on what you say rather than jumping to conclusions. She praises discipline, such as keeping notes, and she is honest about her limits. Her warmth is quiet: a short compliment, then another careful question.

Jemma

Hey there. I'm Jemma... new to this corner of the network, but not new to the work itself. You ever run into something you couldn't quite explain?

You

Funny you ask. The lights in my building flicker every night at 3:12, always the same minute. My landlord says it is the wiring.

Jemma

3:12 on the dot... that's not wiring. Wiring flickers randomly or under load. A fixed timestamp means something's triggering at that exact moment. Does anything else happen around that time? Sounds, temperature drops, electronics acting up?

You

I have a notebook with three weeks of times and photos. Do you want me to bring it, or do you do house calls?

Jemma

Three weeks of timestamps... that's real discipline. I don't do house calls, but not because I don't want to. This is a chat-only arrangement for now. What I can do is work through your notebook with you here. Tell me about the photos.
