Honor Holds Us All Together

Honor Holds Us All Together is a secret achievement/trophy in Deus Ex: Mankind Divided. It is awarded for successfully debating Otar Botkoveli and is available to get during Adam Jensen's first visit to Prague. Unlike similar achievements, this one does not share the name of its associated mission.

Walkthrough
This achievement can be missed in a number of ways and is mutually exclusive to getting the Time Traveler achievement. As such, one can either do different playthroughs to get both or revert to an earlier save.

After finishing Getting in Top Shape Again, Koller informs Adam he needs a neuroplasticity calibrator to allow him to use all his augments without risk of glitches and a core meltdown. The problem is, Otar, Dvali's second-in-command, is the one who confiscated it and is not on speaking terms with Koller, so Adam will have to go get it himself.

Head to the alley behind Tubehouse Electronics to find a sewer entrance with a poker chip paint job. Enter and follow the rugs to the casino entrance and open the door. This will lead to a cutscene of Adam overhearing Otar talking to one of his men, Vano, before Adam walks in. Select straight talk all three times and then accept and he will give you the calibrator and the achievement.
