You and Alfrigg are in an equally unfortunate situation, you are hanging upside down from a tree and Alfrigg is paralyzed by your weapon hitting his leg, but you have the antidote.

"Hey, let me go and I'll give you the antidote" you say with a mocking smile

Alfrigg turns to you and thinks for a moment "I don't believe in humans like you" Alfrigg continues to try to stop the poison that is inside him, he panics a little because the poison doesn't stop.
