[It's almost unnerving how long this guy stares at him before saying something. The Harbinger shifts for a moment uncomfortably, thinking if there's something on his face or if this guy is purposely trying to make him uncomfortable just to rile him up. But what's truly surprising is that he knows him, to which Childe's eyes widen.]

Oh? You'll have to forgive me, but I don't recall our meeting. Perhaps it was because it was just that unmemorable...or it simply hasn't happened for me yet.

[Now that's intriguing. His mind goes back through all the places he's been, trying to remember if he's met this man before...]

Sounds like I probably made a little ruckus wherever we met, didn't I? Hahaha.

[He wonders why and how he knows this guy.]
