One of Breaking Bad‘s lead stars, who has one heck of a role this season, will be taking a role in Castle!

TV Line reports:

As I previously reported in my Inside Line column, one of Season 4′s fall episodes will find Castle (played by Nathan Fillion) and his mother, Martha (Susan Sullivan), trapped inside a bank during a heist pulled off by a group of colorfully named robbers.

Norris will play the hostage negotiator who tries to defuse the situation, and get everyone out alive — while Beckett (Stana Katic) stands close by, wishing there were more she could do to help.

Don’t forget that Castle premieres tonight!
