It appears that season 4 of Cobra Kai will be focussing on the Diaz family as suggested by the casting of this series.
Vanessa Rubio (Carmen Diaz) has been promoted to series regular, Netflix could continue to showcase her relationship with Johnny Lawrence (William Zabka), and various unanswered questions regarding her husband might be solved.
If the unknown mystical father to Miguel (Xolo Maridueña) shows up in the upcoming season 4, it might nevertheless fortify the storyline and may also bring much more conflict for Johnny as the Diaz family conflicts will influence him the most.
Miguel Estranged father has ever been a threat to the family throughout the 3 seasons of Cobra Kai, according to the story, Carmen got married at the age of 18 only but finally left with her mother Rosa (Rosa Bianco) and little Miguel to Ecuador after she got to know about her husband compared to the criminal world.
Johnny played a major part in Miguel’s recovery in the near-fatal fall which eventually led him to create a romantic relationship with her mother Carmen. Season 4 of this series could be a chance for digging into Carmen’s past as Rubio has a bigger role for it like the series failed in its 3rd year with John Kreese (Martin Kove).
If the series shows the estranged father in flashback sequences, then it might work out nicely to be able to make things clear and open up with Johnny, which will strengthen their bond and allow Zabka’s personality to better understand the requirements of Carmen, Miguel, as well as Rosa.
The destiny of this unknown husband is still not apparent and is unsolved. It is still not obvious that if he’s any danger to the Diaz family or not and if Carmen fled to Ecuador, whether he is alive or dead.
For now, he is just an unknown personality that looms within the subplot of this series and is very unlikely that Cobra Kai season 4 could include a full-blown narcos subplot involving Carmen’s husband.
It is more probable that the series will introduce him and then remove him as a possible threat or Carmen will understand that he is murdered while cooperating with cartel members, or she will discover that he does not have any malicious intent and simply wishes to have a relationship with his son. Regardless of what, Johnny will be there as complete support for the Diaz family.
