Abel stops in the doorway at the sight of Cain on the bed, gloriously naked. It's quite the sight, and Abel can't help but think of some kind of predatory large cat: beautiful, dangerous, and lazy. Cheeks reddening, Abel takes a couple of seconds to look, and then he cuts his eyes away and goes to his suitcase instead, unpacking a couple of things until he gets to his pajamas.

He knows it's inevitable that Cain's going to watch, and he doesn't want to seem prudish by locking himself in the bathroom to change. So he lets the towel drop but keeps his back turned as he dresses in soft white pajamas and then heads for the kitchen again, ignoring Cain.
