Couple more items (spoilers)

The money lender Celile uses the runenemy.bcs script, which causes him to flee the red-cicrcled guards in the Copper Coronet events. Sometimes, he runs outside, which lets him avoid the scripted DestroySelf() in ar0406.bcs during the Moiya quests. Bit awkward to have one of his thugs inform me I can't find him when he's around the corner. Or worse, killed in Brynnlaw and yet still hanging around the Slums.

One other item... after Surly moves to the Sea's Bounty, you can threaten The Thumb to call the authorities on Surly, and he agrees to get rid of him. A global gets set, but nothing ever comes of it--Surly remains no matter how many times Thumb agrees to get rid of him.
