Sagan would most likely have protested against being checked by a doctor. This was slightly due to his fear of strangers, but also his fear that if the doctor found anything that had to be fixed, he'd most likely be separated from Kate. Too bad he didn't really have a say in it, as he was still unconscious. It was rather strange how dependent of Kate Sagan had become, especially considering how he'd spent most of his life by himself. He was very unlikely to leave her voluntarily, and it'd probably require chaining him to stop him from trying to follow her at this point.
