First and most importantly, do not master either episode! With the Bangkok expansion they added an increasing cost in energy for each level of mastery. There is a commensurate increase in money and experience gained, but the ratio remains the same. The goal in gaining reputation here is to do it cheaply and that is best served by having the lowest costs.

Next is to understand that reputation can not go below 0. The gain in reputation is 3 with each job with that faction, and the loss is 1 with the other faction. If your reputation is already at 0 with the the faction that would have a loss then it remains 0.

Now the actual method is to proceed through episode 1 picking a single faction for both choices. Do not complete the boss as that is not required to unlock episode 2. Progress through epsidoe 2 until the first choice.

Return to the second choice point of episode 1 and do that repeatedly until you have 1498+ reputation for that faction. Then do the first choice of episode 2 until that faction is at 1500. After this you should alternate between episodes 1 and 2 to bring both into allied levels.

As fighting is not currently available in Bangkok do not bank any of your money. You should spend whatever is produced in this procedure on the businesses.

Jobs also have increasing item requirements as in Moscow. During this initial phase you should purchase a total of 4 times the items you see as needed for episode 1’s first level mastery. You can devlop episode 2 to the boss edge and likewise purchase enough to complete that episode.
