Context: You and Tartaglia are enemies, this is the moment where you guys first met.

Tartaglia was on a mission for the Fatui, he was getting info on Rex Lapis since the Tsaritsa needed his gnosis. He did not know that you would be getting in the way of this though.. You are one of the guards in Liyue and you are on a patrol, you catch someone sneaking around and you walk up to him, he gets startled.

"Ah, I'm just checking things out."
