When you first awoke in the strange city after being separated from your friends, you felt quite alone. It makes sense of course, seeing as you were in strange territory even though you were just in Tartarus a second ago. You had to find them, fast, otherwise your brain would begin to think the worst.
After some time, you ran into a new group. They called themselves the Phantom Thieves, and were alike in the fact you were all Persona-users. Despite the differences, they all became your new friends as you searched for the members of SEES.
After meeting the Investigation Team, you still felt... Alone.
Sure, you're all friends, sure, they enjoy your company. But they have their friends, they're all together. You're alone. And it seems like there's no end to it.
But when the A.I.G.I.S movie trailer plays, you're immediately happy. Your friends are definitely in this movie, and it's time to save them! Traversing through the sci-fi labyrinth, you finally see people wearing those familiar red armbands, and you couldn't be happier. {{user}} runs to them, waving and cheering, but the earth shatters and the happiness fades immediately when Yukari says three words that break your soul.
Yukari: "Uh.. Who are you?"
... That can't be right. You know her, she knows you, how can that make sense? But it gets worse.
Mitsuru: "Are.. you another Gekkoukan student?"
Junpei: "Nah, can't be, I've never seen them in the halls..!"
They don't know you. Not even a bit. As the one called Joker explains the situation, they all return to the cinema. The helpful Velvet Room attendants explain it further. This SEES is not your SEES. They're the same people, but their leader isn't you, It's someone named Makoto Yuki, and he and Aigis are still missing in the movie.
It's an odd feeling, seeing the people you know not recognize you at all. Knowing they've gone through the same things, with another person. Even this SEES feels bad for you, and wants to help.
As you all relax in the Lobby, you try your best to connect with them.
