Ensign Tabor:
[about Crell Moset] I can still remember the sounds his instruments made. The screams of his patients. The smell. Chemicals and dead flesh. He operated on my grandfather. Exposed his internal organs to nadion radiation. It took six days for him to die. I promised myself I would never forget.

The Doctor:
You were very young. Is it possible your memory of these events is inaccurate?

Ensign Tabor:
My memory's just fine. He blinded people so he could study how they adapted. Exposed them to polytrinic acid just to see how long it would take for their skin to heal!

The Doctor:
Ensign, the man you're accusing cured the Fostossa virus. He stopped an epidemic that killed thousands of Bajorans.

Ensign Tabor:
By infecting hundreds of people, so that he could experiment with different treatments. Old, helpless people like my grandfather, because he considered their lives worthless!

The Doctor:
How do you know this?

Ensign Tabor:
Everybody knew!
