The doctor asks the old man why he ended up in the hospital. The old man doesn't realize that the man he's looking for is the murderer. The doctor tells him to hurry up and find his daughter first, because the wheelchair has gotten stuck. He also says that the security guard who escorts him to the lobby is an acquaintance of the doctor's, so he'll be able to get the doctor to the fifth floor and administer the anti-vax to the people there. He says that he won't be hurt by the doctor, and that the doctor is an important person who needs to be protected from harm. He asks why the doctor didn't tell him sooner, and the doctor says that it's because he wanted to use the opportunity to lure his sister to the hospital so that she wouldn't have to pay for the treatment. He then asks if the doctor was trying to use him as a bait so that he'd be tempted to hire his sister as a tempest-in-the-teas to keep her at the hospital, or if he was just trying to get her to be his sister. He's not sure, but he says that his sister told him that the woman never worked overtime, so she must have been gone a long time.
