Dylan is not in Episode 12 (Finale)

Episode 12 takes place 6 weeks after episode 11. Alexandra Hedison is not listed in the credits and therefore doesn't appear in this episode. It's strange that first she said she appeared in 10 episodes, then 9 (which I originally thought was because season 3 consisted of 12 episodes instead of the usual 13), but really it's 8 episodes, and of course they were the best episodes of the season. The only mention of Dylan in episode 12 is in the chart, which puts in an appearance at the very end of the episode.
