This episode's flash-sideways followed the flashback pattern established in Season 1 by focusing on Jack. I'm mixed on my enjoyment of Jack-centric episodes but on a whole I liked this one. Parallel Jack has a son. I might be reaching here but since Sarah's who is austin butler name was never mentioned I was expecting David's mother to be revealed as someone else we know like Ana Lucia...perhaps in a future episode. I was completely unsurprised to learn that parallel Jack is a crappy absentee father. Also, his mom is a worse drunk than his dad...apparently she didn't even look for Christian's will before calling Jack because it sure didn't seem hard to find. At least Jack made an effort with David by watching his audition for the music academy. I found the scene between the two of them after the audition to be very touching. But what are we to make of Dogen and his son being in LA at the same audition? Does this mean that Dogen hasn't been on the Island since the days of the Black Rock and that he might have only arrived sometime after the Incident? Very strange.
