Yeah, I'm also a little worried about the timing with the retching man, and I do want to have that conversation if it's still available.
With the thief down Canary Lane, I'm guessing it's probably someone who either knew the victim or the killer, or was somehow associated. Which would be a great opportunity to get a little background information.

I read on a youtube comment someone's guess about this game. It goes on right up until the time of the upcoming Panel. So the events of this game lead up to that presentation. Since the last two major things have been Ketheric and Gortash, it's reasonable to think this might be the reveal of the third chosen of the Absolute.
I think the overall idea is that Ketheric is associated with Myrkul. Gortash is representing Bane, and finally, the third antagonist to be revealed, is the representation--agent, if you will--of Bhaal.
I buy it, I think they are right ! I even bet the third is a kind of shadar-kai assassin/soul monger
