I see them clashing if Elektra gets involved. She is an assassin and Frank will probably target her in this universe. Matt will mostly likely have encountered her first and started to bond. So when Frank is set to kill her, Matt has to intervene. Frank may also provide psychological dilemma we have seen before. He has no problem killing the bad guys. Frank may watch Matt's actions and question why he doesn't go that extra mile for a permanent solution. It will really have effect if Fisk is reintroduced and Frank will be like if you just killed him before innocents wouldn't be suffering now.
