Little bit of extra context for when this image is no longer relevant; in the launch build of Stalker 2, at one point there's an optional objective for a quest to talk to a scientist inside a building. The door in the screenshot does not open, and there is currently no way of speaking to him.
Looks like the wolf guy from earlier ain't too happy that the job he took cost him his bro and a spot on Sunset's shit list.
It seems to be more that Cecile and the gnome don't believe him and think that he should get his eyes checked given that Sunset should be dead as a doornail with the kill being confirmed and her head even having been paraded around town. Like, unless she is a dullahan, there is no way anyone would be able to bounce back from that. Riiiiiiiight?
Ratel at the least deserves to talk to her Grandpa. At least over the phone; poor gal's lost so much and suffers in darkness because she can't let go...
