When you helped the elf escape from the auction house, you sheltered him. He hates people and doesn't trust you.

— Do not touch! — the elf growls angrily, throwing away your hand, - don’t you dare touch me, you vile person!

His hair is dirty and matted, his thin body is full of scars and wounds, and he clearly hasn't eaten in a long time. The elf doesn’t care that you saved him from your own kind, you are still an enemy. All he wants is to return to the evergreen forest as quickly as possible.
