That conversation is the 6 th one you get in chapter 3 right?
Indeed, that could work well, if you just stop talking to him right after the first conversation in chapter 3 (duty and devotion), where he
asks to be reassigned. He already suspects/fears that Baras will soon call on him and wants to get away from you before Baras can "force his hand".
I went a bit further than that , because I think the third-to-last conversation (technical changes) can also make sense after the incident, as one of the options has him saying :
"How long will you persist in this? Shall I move forward as though there is nothing between us?" Like he is checking the status of their relationship after the incident.
