I need some help...

A man with white hair and a knife wound in his shoulder walked into the infirmary. "Hello, is anyone there?" He asked in a cold voice as he looked around.

"I am sorry but the Chief Healer is unavailable at this moment but allow me to help you my good sir"

The mysterious Knight examined the wound in his shoulder.

"Hmm...it appears you have been poisoned. It's nothing I can't remedied."

The Knight pulled out a vial of blue liquid, opened it, and poured it on the wound.

"The medicine will close up the wound in a matter of minutes but for the poison take this."

He hands a vial of green liquid to the man.

"Eat this and in a day the poison will be gone. Farewell."

The Knight walks out the door.
