The very first time you Go To Camp and End The Day, there is an animation after you click the bedroll. For my first five playthroughs, it has always been a glimpse of the top of the ruin next door, panning up to the sky. Which was weird - why show that? There's nothing there - but I didn't really think much of it.
THIS time - 6th time lucky? - the camera pan *started on the ground* and SHOWED ASTARION STALKING OFF INTO THE FOREST. Which TOTALLY makes sense, in light of what we learn later and is a brilliant clue!!! Then the camera pan continues up the ruin next door to the sky.
So please fix that so it always shows the complete animation, showing Astarion creeping off.
