I've recently finished watching the fifth season of Homeland whose fifth episode is entitled Better Call Saul, which of course is Saul Berenson's first name, one of the main characters of the show played by Mandy Patinkin. But, since the coincidence is so weird, I was wondering if the episode title is also a reference/homage to the namesake series (which is a spin-off of Breaking Bad), although, as far as I'm aware, nothing in the episode's plot seems to allow a connection.
Does anybody have any evidence of the fact that Homeland's fifth episode title was meant as a reference to Vince Gilligan's series?
