Thunder sucks. He can't accept that you are better then Whisper, and him. He is just jealous, and I hate him for that, even though that is the way they designed his character. I still think you should be able to use the lightning spell he does.
btw, I have beatin Fable 13 times, and TLC 28 times. Nowadays, I just get bandits from Twinblade's Camp to follow me, then raid Oakvale, it beats doing nothing =P
Hey Y'all
