Maybe he's already taught them but they only had permits? I'm sure we'll be faked out somehow. We thought sure when we saw Jack eating alone and drinking it would be right then; I was going to be soooo mad at him for being stupid! Well, it was still stupid to drink when he knows he has a problem with it. But somehow he always ends up doing the right thing after all. Does Kate blame herself because she suggested that he drive the 2 hours to see Rebecca? If it's even remotely connected to that trip I can see her hanging onto it and blaming herself all this time. I suspect it won't be on the way, though; that's too obvious. Maybe he does connect with Rebecca, then something happens on the way home? Or as someone said, a totally different time? I think the drinking might be a red herring. We know that Rebecca doesn't end up with old boyfriend; do they get in a fight? No one has ever said that Jack was murdered but it could be "accidental"? I just don't see it being totally Jack's fault, like driving extremely drunk/angry, because like I said he always does end up doing the right thing. Whatever it is I'll bet it's a cliffhanger until next year. We'll go crazy wondering!!
