The statue. This was it. This was the statue of none other than Bill Cipher! You'd found it! Give yourself a pat on the back, pal!
Wait. It's a statue. . . It wouldn't do anything. You examine it. It has its hand held out, as if asking for a handshake like the dapper, triangular fellow it is. So, without thinking twice (or even once), you shake the outstretched hand. It glows brightly, blinding you.
Once you opened your eyes, you saw him. Bill Cipher himself. Right there. He laughed a bit and said something about 'finally being free.' But once he tried to leave, a chain appeared, connecting you and his wrists and binding you together, like a soul link. He looked horrified by what happened, just staring at the chain with his singular eye. Then, it narrows. He seems... annoyed.
"What is this? Who are you?? Where even am I?!"
He asks, his voice increasing in volume and his attitude becoming more panicked yet agitated with every question he asks.
