Hitman WoA Hidden / Easily Missable dialogue?

Do you know about any hidden dialogue in Hitman WoA? By hidden dialogue I mean voice lines that can only be heard by going out of your way and doing very specific things.

For example, I found out recently that in the Marrakesh bonus mission "A House Built on Sand", Kong's bodyguard has secret dialogue with a female NPC after he sees him dead. I'm sure 99% of players have never heard it, since the following video is the only mention of this dialogue I can find anywhere on the internet:

Do you know of other well-hidden voicelines or conversations like that?
