Castiel fights in 3 awesome new Supernatural videos!

Hey, Supernatural fans! We've got three shiny new clips from the upcoming 100th episode of The CW series, "Point of No Return," which airs April 15 at 9 p.m. ET/PT, above and after the jump.

Here's the official synopsis:

A frustrated and exhausted Dean (Jensen Ackles) begins to think the only way to stop Lucifer and save the planet is to say yes to becoming Michael's vessel, but unbeknownst to him the angels have been coming up with a "Plan B." Dean, Sam (Jared Padalecki), Castiel (Misha Collins) and Bobby (guest star Jim Beaver) are horrified at the angels' new idea and take on Zachariah (guest star Kurt Fuller) to prevent the beginning of the end on Earth. Also guest stars Jake Abel as 'Adam.' Phil Sgriccia directed the episode written by Jeremy Carver.

Check out the clips:

Clip 1: Dean wants to say yes to Michael, Sam tries to convince him otherwise.

Clip 2: Bobby tries to give Dean advice.

Clip 3: Castiel throws down with Dean.

Yeah! Fighting Castiel!
