The Sentinels A long journey

Winchester looked shocked and disgusted. "Pretend? I left because I thought everyone was dead. Of course I cared!" he sighed, then said, in a waivering voice "But...I won't deny that it was, partly my fault. Believe me, Cas, please. I thought I was doing the right thing. I...I never would have guessed it would happen like this." His emotions crashed around inside him, but he covered them up. Couldn't let Cas see. Didn't want Cas to worry.

Winchester could see the obvious emotion in Cas. His friend had never been the type to cover up what he felt, or at least, that was what Winchester thought. Winchester felt much more secretive when he compared himself with his friend, and he also felt bad about it.
