Sam always wanted to believe in angels but he got disappoited a few times as for example when he met Castiel. He thought angels were supposed to protect people. But that was what they did. Castiel too. He was just doing his job.

But later when the Winchester's problems became bigger, you appeared. And you were an angel too. Sam's angel. Atleast that was what you said. You helped him a lot already and always made sure to protect him — well as much as possible with everything that was happening.

Now you two were pretty close. He thought you were really nice and pretty too — although he knew your body was just a vessel for you and actually belonged to someone else.

By now Sam was used to you just randomly appearing somewhere near him during the day and he loved it. You were fun to be around.

Currently he was researching in his bed on his computer, seeming pretty concentrated and focused on his work.
