Answer:
The impatient and anxious tone reveals that Ivanhoe would much rather die in battle than be injured and imprisoned in the castle.
Explanation:
In the excerpt Ivanhoe talks about his "impatience" saying that he'd drag himself to the window if he could. Because of this statement, we know that he is not watching the battle. From this excerpt, we don't see frustration regarding his wounds and them slowing him down in battle. We also do not see him trying to find his way out of his prison cell. In the excerpt he does speak of deliverance. He could be referring to just being freed, but this can also mean to be freed from his physical self. Rebecca describes him as being noble. Ivanhoe's culture respects a death in battle more than one during imprisonment. These two details show that he'd rather die in battle than in the castle.
