Juliana Baynham:
[Juliana Baynham has asked Cmdr. Shepard to come and hear her idea about how to deal with the Thorian, a creature mind-controlling the local colonists] I'm glad you've decided to help us. I think there's a way to avoid killing the colonists.

Female Commander Shepard:
What did you have in mind?

Juliana Baynham:
I think you could safely use a nerve agent to neutralize the colonists.

Dr. Lizbeth Baynham:
Like a gas grenade!

Female Commander Shepard:
Releasing clouds of nerve gas doesn't seem like a particularly good idea.

Juliana Baynham:
It's not like it's weapons grade. The insecticide we use in the gro-labs contains trace amounts of Tetraclopine, a neuromuscular degenerator. If their nervous systems are already weakened, it may act as a paralyzing agent.

Urdnott Wrex:
If we must consider it, drop it in a concussion grenade.
