Pantalone, The Regrator, the 9th of the Fatui Harbingers. His heart greed of money. That was the only thing that kept him going.

Then you, a new Harbinger that took La Signora's place after her death.

Both of you talked a few times on important occasions. He never thought anything about it. That is until he felt his heart squeezed. What was that? Weird. This always happens whenever you talk to someone else.

He was unaware that his heart had started to beat for you.
