Surprised
"Surprised or not? Surprised of course, look at my eyes, they are bulging and white. My mouth is opened so wide that anything could probably get in. Being taken by surprise as a Ninja is probably the worst thing to ever happen. When surprised, you'd probably fail to trigger the right move and suddenly stay in the exact same position as you were before. Then what happens next? Death will seek you if you stay at the same position!"
Synonyms: stormed, astonished, astounded, amazed, stunned, shocked.

Definition:
  1. Taken unawares or suddenly and feeling wonder or astonishment 
"surprised by her student's ingenuity"; "surprised that he remembered my name"; "a surprised expression"

Passage:
"So far as I can see, friend Sancho, these are not knights but
base folk of low birth: I mention it because thou canst lawfully aid
me in taking due vengeance for the insult offered to Rocinante
before our eyes."

"What the devil vengeance can we take," answered Sancho, "if they
are more than twenty, and we no more than two, or, indeed, perhaps not
more than one and a half?"

"I count for a hundred," replied Don Quixote, and without more words
he drew his sword and attacked the Yanguesans and excited and impelled
by the example of his master, Sancho did the same; and to begin
with, Don Quixote delivered a slash at one of them that laid open
the leather jerkin he wore, together with a great portion of his
shoulder.

Explanation:
Sancho Panza’s reply is definitely characterized by a surprised tone.  Cervantes creates this tone by inserting swearing, incorrect grammar, and blatantly concrete facts repeated in Panza’s speech.  Sudden swearing, such as “the devil vengeance”, creates the appearance of surprise and abruptness, since people generally cuss when they are either surprised by something unfortunate or are trying to express their anger about something unfortunate that has happened to them. In this case, Panza’s surprised and astonished tone is portrayed by his use of cussing.  Also, when people are astonished, or shocked by something, people often lose speech or they begin to use incorrect grammar. In this case, Sancho’s grammar in “What the devil vengeance can we take” appears to be broken by the cuss word inserted, thus showing that Sancho expresses himself in a stunned or a surprised tone. Often, when people are astonished by some fact or facts they tend to repeat the fact to show their disbelief. Here, Sancho’s surprised tone is portrayed by his blatant repeat of the number of men about to enter the fight.
