Yes, Borge's affection upgraded twice. But I didn't activate the CG scene throughout the game. Also before I played the story, I checked the game interface including the memory gallery, Borge's picture already unlocked.
I did't activate the 2nd Borge CG either. I shooted the arrow in the night, grabbed Tomas, and had red flowers. But I can see the Borge's picture (including 2nd CG) in the memory gallery before I first played.
