Change your smoke detector batteries:
"Something Nice Back Home"

After the roller coaster thrills of last week's episode, I thought "Something Nice Back Home" was a bit of a slow-down.

Before I delve too far into the plot and details of last night, I have a new theory: dead people on (and off) the island are all the same person/thing. Could it be possible that every time someone sees a dead person (like Jack's dad, Charlie and next week's Jacob) they are actually seeing someone or something (smoke monster) that projects an image of the dead person.

Maybe there is technology on the island that allows a person to look like someone else OR maybe the smoke monster is able to look like a person. Remember when Mr. Eko looked into the smoke monster and saw all his own memories and thoughts, including images of his brother? Could smoke monster be capable of more? Was the smoke detector's failure in Jack's office a hint that smoke monster was there? It's all nano-bots, I think.

ANYWAY, here's what I was left with last night:

• The promos for the show drive me CRAZY! "The island claims one of the survivors as its own." What? Was that Claire? What does that mean? Is she dead?

• I don't think we've ever travelled past the point in time when Jack and Kate meet at the airport at the end of season #3. Time jumps on the show seem to occur in the space prior to that and after the 6 are off the island.

• Sawyer may be alive in the future. Kate seems to be talking to him on the phone.

• Jack's addictive behavior seems to be aided by jealousy of Sawyer.

• Are we finally convinced Jack and Claire are step-siblings?

• Why did the island let Jack get sick?

• Jack is an irresponsible pill taker! Never mix meds with alcohol!

• Dan is still irritating. Jin, please break his fingers like you promised Charlotte.

• Jack's proposal to Kate was a nice moment.

• Jack was reading Alice in Wonderland to Aaron. Is this a clue?

• Hurley tells Jack in the future that they are already dead. HMMMM.

• Miles can see dead people. Or, at least, he can see the past. Is Miles a time-shifter like Desmond?

• When Juliette told Kate about Jack kissing her, I almost punched the TV. But then I realized her intentions were good. This proves my theory: Juliette's a blabber mouth, don't tell her anything (or kiss her).

• I feel the most sorry for Hurley. He needs something good to happen to him.

• Sawyer is standing up for everyone!

• We might now have a clue how Sun gets off the island (Jin's threat to Charlotte).

• Russo and Carl are really, really, really dead. In-the-ground dead.

• Next week's promo finally shows us Jacob. Sigh. Why show him in the promo? He DOES look like Eric Stoltz in "Mask." REMEMBER: Jacob is dead. What we see is really just smoke monster pretending to look like Jacob. That's what I think.

• Change your batteries in your smoke detectors! It's saves lives, sanity and a fortune in prescription medication costs.
