He'll tell you that he's tired if you keep talking to him. At that point, get some Imperial Coffee and give it to him. Since you only gave him cure 2, you'll need to do this for a few days before he'll be finished. If you had given him Cure 5, you'd only need to give him coffee once.
OK... I traded the Scroll of Cure2 and the White turbin for this on the 28th, and today is 9/1 and he is still saying "I have just begun working on your order's artificial intellegence nodes.... ECT" that makes 4 days! how long do I have to wait?!?! Is it just me or is others waiting on this for a number of days too?
