Castle

Dean Norris will remain on the right side of the law for an episode of Castle this fall.

The actor, who is unknowingly on the hunt for his brother-in-law as a DEA agent on Breaking Bad, will guest star on the ABC hit as a hostage negotiator, according to TV Line.

No air date has been announced for Norris' appearance, but the installment will find Castle and his mother inside a bank while a robbery takes place, and Beckett looks on helplessly.
