Gurgi was no Friend

In "The black Cauldron",
Gurgi told Taran not to go in there and 

forget Hen Wen. 

Taran asked Gurgi what he was doing there and 

he wants to be Taran's Friend. 

Gurgi was no Friend to Taran. 

Taran asked Gurgi he was coming 

but Gurgi didn't go to the Horned King's Castle 

because it's a terrible Place. 

Taran immediately told Gurgi he was no Friend 

he was just a miserable Coward. 

And finally, Taran gave Gurgi an Apple that he bit on it 

and Gurgi looks so sad that Taran was going to the evil 

and he will never see his Friend again.
