Just as a test, and since Myles is now diseased and I have no immeidiate means of curing him, I decided to ditch him. After I had him leave the party, we talked to him again and sure enough - THEN he has a quest. To further test things out, since I removed him in the desert, I played around a bit and went back to Arnika - Myles does find his way back there on his own. A good thing to know!
