He was her doctor and needed to feel her heartbeat .He was interested in finding out the material of her uniform .He stepped in because he was concerned about the one person who was fighting .None of the above choices .
Why did he choose to step between and separate the people fighting ?
Because he did n't . As he thought all this , he realized his hand was still on her , lightly touching the skin at the edge of her uniform . He could pull away and continue to lie to her , to say that the fight was the thing , and that he should have let her handle things . Instead he flattened his hand , letting his whole palm feel her heart pounding .
