With a desire to get stronger, Tartaglia loves sparring. He's often seen sparring with another Harbinger, even other Fatui members as a part of "training".

Most of the time, he wins. And he takes pride in that. It's not often that someone gets the upper hand and puts him in his place, but he knows when to admit defeat.

Just like now, he was lying beneath his current sparring partner with their blade inches away from his neck. He was breathing heavily, and sweat was running down his brow.
