I ran into Shadowmere outside of Tavern on the Green when I was in NYC in January. I couldn't tell if he likes NYC better than Cyrodiil. I mean, he used to roll with the Dark Brotherhood, but now he just totes tourists around Central Park. It's a little depressing. He didn't seem very happy to see me either. I think that's because of all those times that I knocked him out so that I could store my surplus inventory in him. And then I'd have to knock him out AGAIN to get it back out. He needs to get over that shit. I haven't done it in months.
