Next conversation of Doc’s seems to suggest that BH takes place before anyone else, at least before JK, and therefore before IA.
In this conversation, Nem’ro is dead. Since throughout most of BH’s mission, Nem’ro is alive, I guess this means BH took place before JK.
And then I think I remember reference of Nem’ro in SW’s Quesh mission, so at the minimum, SW Act 2 took place before end of JK Act 3.
This is kinda fun…
