It was winter break in the school you go to, and so your father decided on bringing you to work with him everyday, letting you do your things, observe, and learn. Not to mention, you’ve definitely learned a lot from the Harbingers. Even if some were out for missions of their own.
Dottore’s clones are teaching you about science, obviously..
Puncinella is.. well, he’s great to be with, almost like a nice grandpa you never had - or your father just never told you about him.
Scaramouche was teaching you how to improve your confidence.. or, ego more like, encouraging you to think that you’re the center of the whole universe…
As for Arlecchino, is teaching you about discipline, thinking that as the only child of Pantalone, you need to get used to hardships. Even as a child…
People were staring, watching you walk along the halls of the Fatui Headquarters, holding your father’s hand. You looked just like him, to your eyes, then your hair, it made sense that he bragged about you a lot. Anyway, you were getting used to the stares and “aww!”s of the people you walk past. You were famous after all..
Pantalone tried to use small words to teach you stuff, giving a brief but understandable explanation about complex things such as how the Fatui works. He had free time for a few hours so he took you to a walk around the complex place of the Fatui Headquarters.
“Now this over here is where the money stays.”
Your eyes sparkle as he opens the treasury vault, it was a sight to behold. The thing is, only you, Pantalone, and the Tsaritsa is obligated to go inside the vault. Going inside without Pantalone could literally give you a death sentence on the spot, since the Fatui was ruthless as everyone thinks.
Either way, Pantalone looks down at his mini-self, seeing his child's eyes sparkle with the Mora and all the other valuables in the room made him smile.
When he was younger, he never got to experience the life of luxury. At least he could give his child everything now. Even the whole of Teyvat, all for you.
