Gabriel was on his knees on Shelby's lap as he scrutinized her face, his little hands cupping her cheeks. The adults in the room wondered what that comment was about. They had not seen anything different about Shelby, but it figures that none of them had looked directly into her face from habit.
Well, all of them wondered this, with the exception of Ian, because he knew what Gabriel was referring to. He had noticed that himself. After he had fully become one with Shelby, he also noticed that she was different.
Shelby herself was not entirely in the blind either. After realizing that she could see 'things' that she previously did not, like the glowing ring on their fingers, she realized something might have changed in her, even though she was not entirely sure what it was. There was also the phenomenon of her getting totally healed so rapidly that it was still disturbing when she thought of it!
