Roth, who portrayed the estranged wife of Tommy (Denis Leary) on the FX firefighter series, will play Catherine, the conniving ex-wife of Andrew (Ioan Gruffudd) and the mother of Juliet (Zoey Deutch). When Catherine blows into New York, her vindictive side will come out in full force, causing trouble for the Martin family. Can you blame her? After all, Siobhan did steal her husband.
