Awww, poor Sammy! ...Right. I will call the Winchester Sam "Sammy". And the Beckett Sam will be "Sam". And Winchester Dean will be "Dean". Unless I'm feeling funny and want to call him "Winny" instead. Although in this chapter "Chester" seems appropriate XD

Okay...so from former "knowledge" and what I got from this chapter, I think that what Sam does, is leap into people and stop something devastating from happening or something, right? And Dean dying is pretty devastating, not only to Sammy, but all of us, so it follows that Sam must save Dean. Awesome :)
