350 hour save file on Xbox 360 and he was my favorite follower. I had him in highly smithed and enchanted Morag Tong armor with an awesome Blades sword. I've taken him everywhere and sent him back a million times. The last time I sent him back he never returned I've checked the Wretching Netch a million times. I've waited weeks and weeks and he doesn't return. I am empty inside. Anyone know where he may be?

Same thing happened when I started a new game, Lydia disappeared hoarding all my nightingale armor :/ Never found a fix, she never returned, poor Lydia.
