The finale of season one will be on May 13 2010, which will be the 22nd and last episode. Most likly they'll take a break to film और The Vampire Diaries episodes so they should be done द्वारा September, and I say that because season one started in September!
The reason they took the breaks is too film और episodes. It's still season one untill May 13! If आप want to कन्फर्म this या get the summary of any episodes आप may cheak her on WikiPedia!
link I got all my information from there, so I own none of what I कहा except for my words, the ideas came from here and I beleive them! All except the September starting of season two, that WAS mine!
