It isn't like he's really kept track of time. "It feels like a long time; I don't know. Months and months. First before I died, just a few times, and then after, and I was here for good. I think I came here because a friend of mine was here and she needed me... but I'm not sure. That sounds too noble when I stop to think about it."

Besides, Sam didn't even ask that question, but he's always been in the habit of giving more than he gets.
