[@Chanda] Considering how Eolas and Oliver would have been put in contact by Eolas' merc contact, wouldn't it be safe to assume that the contact had hired or at least knew of Oliver's actual business?

Oliver would probably publicly advertise himself as a mercenary, but would never admit to being a thief. Eolas may have heard rumors that Oliver has been involved in some shady sneakthievery, but Oliver would never admit to it and there wouldn't be any evidence one could really point to beyond those rumors. A good thief probably wouldn't leave behind much of anything that link them to the crime anyhooooooo.
