- Asato Kido a.k.a. Shadow: You realize how many doctors are in here?
- Yusuke Urameshi: Okay, then we'll just have to knock 'em all out.
- Genkai: Just don't hit too hard. I hate crippling civilians.
- Genkai: This doctor might not work here. Maybe a nurse could spot an impostor.
- Yusuke Urameshi: Clever.
- Asato Kido a.k.a. Shadow: I'll take care of that, you guys.
- Yusuke Urameshi: And I'll check the upstairs.
- Genkai: If anybody finds him, make a noise we'll all hear. Either scream or blow something up.
- Sensui Shinobu: I've staged an interesting test at the doctor's expense. I want to see what happens when Yusuke's group has to battle a fellow human to the death.
- Minoru Kamiya a.k.a. The Doctor: This is definitely my favorite power. I can infect everyone within my territory with a disease of my own psychic creation. I change these demon insects to be my carriers. The weaker the victim's energy, the faster the disease can spread. Your friends will last thirty minutes, and then I'll get to watch them die.
- Yusuke Urameshi: I learned form Kaito about you psychics. Your powers fade when you're asleep - so go to bed.
- Minoru Kamiya a.k.a. The Doctor: No time to sleep. I'm working a double shift.
- Minoru Kamiya a.k.a. The Doctor: As a doctor, anything I can cut I can stitch back into place.
- [the doctor reattaches his own severed arm]
- Yusuke Urameshi: One downside to making friends: You've got more people to protect. I mean, when does a hero say, "No, don't hurt that total stranger, I'll give up my own life?"
