[Cadaverous Pallor]

There are a lot of valid questions on that list. Some are dumb, though.

"Why was Charlie fated to die, exactly? What did Charlie's death accomplish, in the end?" Um, fate doesn't have to have a reason, or accomplish anything.

"Why was Libby in the same mental hospital as Hurley? What's her deal exactly? Why was she in Australia?" Does this really count as 3 questions? First question, um, because everyone intersects in the alt. timeline. Second, I'm not going to dignify with an answer. Third question I wouldn't count as something they "really have to answer". Who cares?

"It seems like everyone who was a passenger on Oceanic 815 has numerous connections that they don't even know about. Like Jack and Claire being half-siblings, and Sawyer's ex-girlfriend helping Kate confront her mom. What caused this excessive degree of synchronicity?" Wow, there may be no dumb questions, but this is a dumb one. Um, because, that's the crux of the show, that it's all about fate, that everyone is linked. It's like asking "why do the Losties keep getting split up and reuniting over and over again?" Because that's the show. Dumb.

God, I hate these lists.
