Princess Vella and her dragon

The following day princess Elena woke up because of loud noise. She stood up and saw a red colour dragon near a river. Princess ran near the dragon without any fear and asked the dragon "what happened to you?". The dragon said, " what! A human, why aren't you scared of me?". The princess said, " why should I be scared of you?". The dragon said, "oh, you are a brave girl, no human had ever dared to come near me, they just ran away from me". Then the dragon said, " I have a thorn stuck to my leg it hurt so much. Can you please help me?". Then the princess took the thorn out of the dragon's leg and asked" did it hurt?". The dragon said, " no, I didn't even notice, you are very kind, Tell me anything you want in return". Then the princess said the whole thing happen about the witch Vella , her plan and how she escaped the cave. The dragon said " Witch Vella, I know her, she once made me turn into a frog and I found out what she was scared of the most, She is scared of mirrors. Saying that the dragon gave a mirror to the princess and said, "get into my back, I will take you to the palace". Princess got into the dragon's back. Then the dragon flew away.
