Very well said! I honestly wouldn't blame anyone for breaking up with him during Revelations. That's a hell of a test to put a relationship through, and sometimes the relationship just can't take that. A friend of mine told me he'd been romancing Blackwall and broke up with him after finding out the truth, although in his case the crime itself seems not to have been the main motivation. He described his character as a "diva" and said he'd started romancing Blackwall because his romance came up early and he assumed he could "hit it and quit it," and that his Inquisitor didn't want to be with Blackwall anymore because dating a Grey Warden wasn't helping to make her more famous anyway, and a fake Grey Warden was useless. The utter shallowness there tickles me. I'm not sure if I could have stayed with him if he had killed Callier's children deliberately. Knowing that he hadn't expected them to be there made the whole mess easier to forgive. What he did was terrible, but he had some trace of a conscience even then, and by the time his past comes out in the game, you've had time to learn what kind of man he is now. (A damn good one, if I may say so.)
The fact that he committed treason purely for money feels to me like an indication that he was always a man who needed a cause, but for the majority of his life he didn't have one, and just had this feeling that he was missing something he needed. Since he had never had a cause to invest himself in, he couldn't figure out what was missing from his life, and living in a society where money was portrayed as a ticket to happiness, he tried to fill that void in his life with money.
I'm sorry you missed out on a lot of banter.
I think one of the patches was supposed to make it fire more regularly? Do you do multiple playthroughs? There are some awesome banters out there, including some good ones between Thom and Iron Bull (since you mentioned Bull falling under the radar for you).
re: the romanced Warden ending in Trespasser. It is fitting, though the vagueness of it still bothers me. Why wouldn't the Wardens include a note? I realize they can't go into detail on epilogue slides, but if the intention really was for him to be dead, I don't see why the package didn't include a note from the Wardens informing the Inquisitor of his death in the line of duty (or, if they wanted to leave that door open a crack just in case, it could say he was missing and presumed dead). The lack of closure there still bothers me. And in my own case, I feel like my Inquisitor's ending already had enough bittersweetness in other respects and that Thom dying just made it too bitter for me, which is why I'm now replaying. That ending makes sense, I just can't accept it. Fortunately I'm better at time magic than Alexius ever was, and can go back and change it. 
Oh, and speaking of Sera, did you read her journal in Trespasser? Her notes on Thom's and the Inquisitor's relationship are adorable!

Thanks for the video! I would never have found out about that!
