Kill Lorbumol gro-Aglakh Resolved Thanks

I just completed the Thieves Guild Quest: Kill Hard-Hart.

As I'm the Champion at the Fighters Guild, I went to see Percius about orders, but I was expelled because I killed Hard-Heart. As this was the 1st time I had been expelled I was forgiven. Then I asked Percius for orders, which were: Remove Sjoring's Supporters. I didn't have to kill Eydis-Fire-Eye, because I gave him  the Bitter Cup. So I only had to kill Lorbumol gro-Aglakh. I went to see him & he started to attack me. I summoned a Golden Saint to aid me, but he also killed the other 2 members of the Fighters Guild, so I was expelled.

I reloaded & went to see Lorbumol again. This time he died because my reflect damage killed him & again I was expelled.

Percius doesn't want to talk to me because I'm expelled. I don't know how to clear my name or make amends. There aren't any options in the dialogue box that could help me. I clicked every chat option.

So I'm stuck. Did I play this the wrong way? The green arrow is still pointing to the Fighters Guild. Could anyone help me? Perhaps I should just remain at Champion level at the Fighters Guild.

Thanks

I reloaded a save where I had to kill Hard-Heart for the Thieves Guild. When I Got there I killed both of them. I was expelled, but as it was my 1st. time I was able to cont. Thus I became Master of Fighters Guild as well.
