when blake finda his own name in the paint staint nightgown he is ?

Can you tell me what novel this question relates to? Pride and Prejudice does not have a character named Blake.

I just realized that you asked your previous question under the question forum for Moonstone. If that is the case, in the Second Period, Third Narrative, Chapter III, we learn that Blake was shocked at the discovery. You might also use the word stunned to fill in the blank.
