- Dr. Alexander Kline: [Someone stole the vial] If the combination of bleach and DS2 won't kill it... Fire and steam will.
- Jonathan Kaye: [Kaye wants Kline's strain] When we find the strain, if we find it... I don't want it destroyed unless it's absolutely necessary.

- Dr. Alexander Kline: I had to gain time... To keep it from circulating in the air...
- [Last words]
- Dr. Alexander Kline: [Kline won't tell McGarrett where the vial is] You think I want people to die?... You think I enjoy that?... Don't forget, I'm gonna die along with everyone else.
