SPN: Scenes I Love . . .

In Sam's first interview with Max Miller, we see the boy looks pale and his skin has a sweaty sheen to it. At this stage, it's easily attributable to the trauma of losing his father, especially because he reveals he found the body. Later, however, we'll realize that using his powers takes a physical toll on him, just as Sam's visions do on him.

Another detail that's dropped in this conversation is that Max is living at home because he's struggling to save for college. Presumably he lacked the intellectual ability to score a full ride, but his desire to go to college at least is something with which Sam can identify.
