What did you do today in DA? [Spoilers]

It appears to be on a ~15 min timer, and anything that causes a loading screen (fast travelling, entering a Villa/underground area/etc) resets the timer, using a mount pauses the timer, entering the menus pauses the timer... and apparently there's also a few spots where banter can't be triggered (Winter Palace, Therinfal Redoubt, possibly the Western Approach, a few other mainly quest-specific places). Banter can be specific to any of the party members, can be related to the region you're in (Hinterlands, Storm Coast, Emerald Graves, etc.), can be quest-related- you'll have to grit your teeth through a few "oh its raining" or "oh its cold" comments that count as your banter for that period before you get to the juicy stuff. But so basically what you want to do is run around (never fast travelling, never riding a mount) with just Iron Bull and Dorian (to eliminate banter about/by someone else)... go close all the Fade Rifts in a region, for instance (it also seems/is reported that closing rifts, completing quests, and finishing fights triggers banter). Using a timer helps keep track of where you're at; its nice to know when you have only a min or two before the next banter, so you know when you'll be able to fast travel or leave or whatever. I also read conflicting things about the Inquisitor being locked into a romance with someone besides Iron Bull/Dorian either helping or being required to trigger their romance, so I locked into Cassandra romance just to be safe.

Anyways, I've now gotten the first banter that supposedly sets up their romance (the "conquer" one), and a few other random flirtatious ones, so I guess so far so good. I wish I had known all this before I did everything in the Hissing Wastes, that would have been perfect for getting this done- so much empty space to run around and kill time (and no quests that require loading screens).
