"CSI" And "Supernatural" Air Season Finales On Thursday

Los Angeles, CA (CNS) - Viewers will have their choice of two season finales on Thursday, the finale for "CSI" on CBS or "Supernatural" on The CW. Of course viewers with Tivo can watch both.

On "CSI," executive producer Carol Mendelsohn told TV Guide to expect, "the most shocking episode of 'CSI' ever." Since past finales have featured Nick buried alive and a shocking revelation that Grissom and Sara had been sleeping together, whatever the folks at "CSI" have drummed up, well, it must be big.

On "Supernatural," Dean is down to his final 24 hours after making a deal with demons a year ago to save his brother's life. Executive producer Eric Kripke told TV Guide, "The boys race like hell to save him."

Kripke also revealed "they know who holds the deal and how to kill them."

He did promise one thing: viewers shouldn't expect everything to get wrapped up nice and tidy. "We leave them in a pretty suspenseful place," Kripke said. "I hope it will drive everybody crazy until we're back in the fall."

Both shows air at 9/8c on Thursday, May 15.
