After all this time, it's still got one show each from its parents:
Supernatural is the last original WB show and
America's Next Top Model started on UPN.
They've basically blown up their schedule for 2013, but it looks like the pieces fell in a good way. Monday is all new with shows that have been relocated. Tuesday takes The Vampire Diaries spinoff, The Originals, and pairs it with Supernatural. Wednesday has the returning Arrow lead into the new The Tomorrow People. (The CW really likes things with 'the' in front of them.) TVD starts Thursday and will hopefully bring viewers to the all-new Reign. Top Model returns to Friday before the somewhat surprising return of The Carrie Diaries. The CW doesn't program weekends, but they are bringing Nikita back at some point, midseason, for a 6-episode final season. Which is a nice gift to the fans since it was the lowest-rated program to return.
Nothing's going to break out, but they'll keep on keepin' on.
