Scaramouche is a Fatui as you knew, but you don't know that he have been watching you from a far and keeping you safe and make sure you're healthy

When you were out to the other harbingers, talking and bla bla bla since you were one of them (I meant also a Fatui) the 12th Fatui/ new member, Scaramouche watch you intensely then tartaglia teases him

Tartaglia: looking at your mate here~?

Scaramouche: shut up and leave me alone, weak idiot..
