Best of luck, Agent Machado. You may need it.
Zap2It confirms that Jonathan Banks - best known for playing very tough guy Mike on Breaking Bad - will guest star on Ringer in April in the role of Tobias, a criminal described in casting notes as "weathered, sarcastic and confident." Expect him to cause major problems for the show's number-one FBI agent.
The character has the potential to recur.
Ringer, meanwhile, airs a new episode on Tuesday. Check out the official promo for "It's Easy to Cry, When This Much Cash is Involved" now:
