Apparently, April 10th will be preempted by a 2-hour episode of "Brothers & Sisters". That sucks... Also, May 22nd will be preempted by the American Billboard Awards (how many award shows are there?), so if the season has 23 episodes (no valid source on that), episodes 22 and 23 might air in the same day as a two-hour finale (which would be a first for the series). If not, if the season has 24 episodes, we might have to wait an extra week for the 2-hour finale.
