This time I checked when I started the Episode and even though I did not go alone at the start, thus had plenty of "timekillers" (dialogs) from the start, the game ended so quick. Hit the credits after pretty much after exactly 1.5 hours.
My other game where I went alone was barely above 1 hour.
Now, most other episodes usually took me 2-2.5 hours on my first playthrough.
I hope they don't keep making episodes that short in the future season.
