I’m not sure I agree with Mark’s assessment of the Center. Far from rich looking, it appears spartan, pedestrian, and not even finished.

Apparently, Rivera wants us to believe that Rex and Tess, returning from their “nature walk,” cannot see Mark peering into the window (once again!) of a somebody else’s private rooms. Nor do they see him running away—arms and legs akimbo—across the grounds, while directly in front of them. Ah! It must be because they are so madly smitten that they have eyes only for each other. If so, I’m surprised that Rex is not wearing Tess’s tiger ears.

This is all confusing. Mark is disturbed. At what, I wonder:  Something inside the building or maybe a reflection of Rex and Tess approaching from behind him? Or maybe he just realized that he should have made a pit stop before setting out on his covert investigation.
