And I'm also more concerned about what it will do to his relationship with Lorelai... which is probably the whole point of this contrivance, anyway

That's the first thing I thought of. I'm really interested in how Lorelai is going to take it, and how it will impact their relationship. I mean, I'm pretty confident that Luke and Lorelai are totally settled and there's really no chance of them breaking up (if anyone knows otherwise, don't tell me!), so I'm really curious about how Lorelai will react, if Luke will be worried that Lorelai will freak out and run, etc, etc, etc... Fun!
