Casey's reaction was subdued. She even had a bit of a delay in turning her head. She did not seem too startled and she even told her attorneys that this is why she said the jury selection should be closed. (It was picked up on the news feed) I did not see a strong reaction or response from Casey at that time. When she left the Courtroom for lunch she was rubbing her hands and arms and even stopped walking for a few moments as if she wanted to delay going back to her cell. ETA: I just read on another thread that the Bailiff's stopped Casey for a few moments befoe going back into her holding cell.
