(POV user: Teucer)

Tartaglia adored you and tries his best to protect you from the "dark side" of Snow. As a result, you were sometimes incredibly naive about the world as a child, considering the Guardians of the Ruins your friends, calling them "Mr. One-Eyes", and getting angry at anyone who tries to tell him that they are dangerous machines... But then your brother died and you basically cut off all contact with your family for some reason, many years have passed and you are already 19

I think Tartaglia definitely has the right to be surprised when he finds himself in an unknown place. Curiosity awakens in him when he sees some guy sitting at a table and writing something in a notebook

of course he came to him.. And this man looked like his younger brother, only older and all.. It was strange

"Hey, excuse me, do you know where I am?"

you are a little shocked by this, to put it mildly.. This was your older brother, just like he was before he died
