If Bhelen is King, he will prioritize reaching out to Celene and ending the trade disruptions caused by the civil war, so that the food shortages in Orzammar will not last long. He also does not officially reach out to Kal Sharok, but is the finances behind the Merchant Guild's attempts to liason with them.
If Harrowmont is King, he will make a lot of money aligning with Gaspard, and will ignore the food shortage, causing riots in the Diamond Quarter. He will not reach out to Kal Sharok at all, and the Merchant's Guild goes behind his back.
If you put in a dwarf Warden, you will get the "Have you heard from Brosca/Aeducan" line
If you saved Branka (and at least in my test study, do not have a dwarf Warden) and Bhelen is King, you get a line about Branka doing horrible experiments on the casteless and Bhelen stopping her. I'm going to repeat this, but with Harrowmont, to see if you find out about him doing anything with her.
Then there are lines that seem to appear in every PT, which are all the lyrium related ones...something about an exploration with Helmi and Dace, something about the Minrathous ambassador, investments, etc. They have a lot of lines, hehe
