Who should I give the fruits
95% it's better to give the fruits to the Bull Tribe so you can prevent the execution of the three Lizard Prisoners. The Survival of the Prisoners is important to "repair" Thane and his relationship with his father.
Have you clicked my link and read my postings? Then you should already know that: Once Axel gives you the last Quest to infiltrate the Liazrd village, you go to the Bull Shrine instead. Inside the secret room enter the mirrors. If you enter the mirrors 3 times and got the Bloody Cloth from Thane, you will unlock a special scene.
