From using Jan's relationship with Donnie against Harry to destroying the Harrigan estate, Frankie's moves were shaping up to be disastrous for the family. In the latest episode, he made his presence known by arranging a one-on-one meeting with Kat McAllister. Frankie revealed that he had bypassed Colin and wished to deal with Kat alone.Frankie's meeting with Kat was fruitful, as she agreed to give him a chance to prove his worth. Kat agreed that if Frankie made another dent in the Harrigan empire in one week, he would officially become her partner in crime.Eager to prove his worth to Kat, Frankie used Sicily to lure Paul into his den in Mobland Season 2 Episode 7. He then used the Harrigan right-hand man to lure Harry into a trap. Frankie ordered Paul to call Harry about an opportunity to capture Frankie at Riviera Palm Casino. While the trap was impressive, Paul cunningly called Harry 'bro' during their conversation, a secret code for both Harry and Kevin. Since Harry hated that expression, he understood that Paul was warning him, and he prepared for his showdown with Frankie at the casino.Harry revealed his ace of spades in Mobland Season 2 Episode 7 View this post on Instagram Instagram PostHarry met up with Paul in Mobland Season 2 Episode 7 and approached Frankie's private table.
