I thought Boone was really acting strange this episode. It's really like what Matt/Jack said about he and Locke being "joined at the hip". I thought it very strange for Boone to attack Michael like he did (I know Michael had a knife...) - but Boone attacking him was very uncharacteristic of him.

Also, every time you saw him he was skulking/sulking in Locke's shadows... Like he was Igor to Locke's Dracula/Dr. Frankenstein.

Maybe the drug Locke slipped him has him "strung out". Any ideas?
