That…that wasn’t exactly the kind of response he was expecting. A Persona is a well-kept secret, at least from his experience. To drop the term would have been akin to some sort of secret code - anybody would have agreed or denied his claims outright. Did this guy opted to joke about it instead? It was certainly an interesting way to go about it.
A switch flipped up in the back of his head. If he wasn’t playing up this facade he would have already squinted at the blue-haired boy in suspicion.
Goro met Kurusu by coincidence, and he turned out to be quite unique in that he couldn’t seem to figure him out off the bat. That connection turned out to be much more. This, however, was no coincidence at all - he approached this stranger with the full knowledge he could summon a Persona. What are the chances that we would meet a similar kind of individual with the similar kind of powers?
Best to play along, for now.
“I know what a Persona is, and I’m quite sure that was no specter. Don’t worry, you’re secret is safe with me. I have one, too.”
> Hm, so that one didn’t work. You’re tempted to keep testing him, but the instant the young man mentions that final detail, your eyes widen just a bit. Knowing about Personas was one thing, but being another Persona-user was a different state of being altogether. The chances of you running into an unknown Persona-user in this place were slim enough to become one-dimensional, but here you are.
> ...You figure Orpheus has been hanging around for long enough, and with a mere thought, the ghostly reflection of your innermost self returns to you. You’re going to need to carefully decide what to say next. Your next response could be crucial to figuring out more about this young man, as well as understanding exactly what he knows.
=> Quiz him on the Dark Hour.
> Before the conversation develops any further, you bring up a number of topics you presume a Persona-user would know about while trying to be as vague about S.E.E.S. and its operations as possible. A series of basic mentions of the terms ‘Tartarus’, the hidden ‘Dark Hour’, and ‘Shadows’ should be enough to give you an idea on the young man’s position.
