The Oceanic 6 were in good company for their journey back to the Island: The electromagnetic pockets of last night’s Lost attracted 11.3 million viewers, up 13 percent from a disappointing performance last week when the Lost gang had to share a time slot with a two-hour American Idol. Lost’s total audience from last night (which also hit a season high in the coveted 18-49 demographic) is about on par with the series’ season 4 average. Meanwhile, Lost‘s followup, ABC’s Life on Mars, continues to sink — its 5.8 million viewers didn’t come close to the 8 million the show consistently attracted during the fall season. Fox’s Lie to Me — which did not air last week due to the two-hour Idol — lost 14 percent of its audience from Feb. 11.
