What is going to be the effect, now that Fain has turned a fade to HIS side, can't remember what happened to it, can anyone show me the light?

This is in TSR when Fain is in the Two Rivers with the WhiteCloaks?

 

He is getting the Fade to attack Taren Ferry and allow people to escape across the river to bring word of the trollocs.  His goal is bring Rand to him.  He is not satified with Perrin alone. 

 

We hear from Luc latter on about the attack and the people escaping but never see the effect of any tales that might bring. 

 

 

Yes, but after the battle, Fain leaves with his 'dirtycloaks' and the fade....cos Fain can't believe the Two Rivers won the battle.

The fade was still well when Fain had it wait for him while he went to the Tower.
