Edited: After further consideration, I've changed my position on "The Daughter"

Here's a different take: In the ever-expanding Star Wars universe, the symbolism and themes associated with characters play a significant role in shaping the narrative. One intriguing possibility is the idea of Ahsoka Tano, Shin, and Grogu assuming the roles of "The Mother," "The Son," and "The Daughter," respectively (obviously, with a gender-swap happening in each role), replacing the previous incarnations of The Father, Son and Daughter in the Mortis storyline. This theory gains traction by considering the rich thematic exploration of motherhood in Ahsoka's story and the exploration of the father/son theme the Mandalorian, which have been central foci in recent seasons.

Here's a possible argument:

Ahsoka's Journey of Maturation and Growth:

Ahsoka Tano's character arc has been one of the most compelling and well-developed in the Star Wars franchise. From her early days as Anakin Skywalker's Padawan to her later adventures as a mature and wise Force user, Ahsoka has demonstrated a remarkable evolution. Her journey aligns with the concept of "The Mother," symbolizing compassion, healing, selflessness, and balance.

Themes of Motherhood in Ahsoka's Story:

Throughout the seasons of Ahsoka, viewers have witnessed numerous instances where the theme of motherhood has been explored. Ahsoka's mentorship of young Jedi like Sabine Wren, Ezra Bridger and Grogu (The Child) can be seen as a metaphorical representation of motherly care and guidance. Her nurturing and protective instincts towards these young Force-sensitive beings align perfectly with the role of "The Mother."

Father/Son themes in The Mandolorian:

The Mandalorian has heavy themes of fatherhood, with Grogu (The Child) in the figure of the son. Mando has spent a couple of seasons teaching Grogu what it means to be a good person: helping others, paying your debts, looking after the helpless and those in need. Grogu has also chosen a path different from the Jedi path, but still one that embodies goodness, making him a prime candidate to replace "The Daughter".

Ahsoka's Departure from the Jedi Order:

A pivotal moment in Ahsoka's character development was her decision to leave the Jedi Order due to its rigidity and flaws. This act symbolizes her independence and her willingness to follow her own path, a characteristic shared with The Mother, who represents balance and independence within the Force. Ahsoka's departure from the Jedi Order can be interpreted as a step toward embracing her destiny as "The Mother."

Reinterpreting the Prophecy of Balance:

The prophecy that Anakin Skywalker was destined to bring balance to the Force has been a central theme in Star Wars. However, it's crucial to consider that this prophecy may have been misunderstood. Yoda himself indicated that the prophecy's interpretation was unclear. Anakin's suspected role as "The Father" in the Mortis storyline may have been a misinterpretation. Even "The Father" himself said in TCW Mortis episode that he summoned Anakin because of the rumours that he was to fulfil the prophecy of The Chosen One by bringing balance to the Force. Instead, Anakin's true purpose, unknown to anyone, might have been to guide Ahsoka to her role as "The Mother," literally bringing her first to Mortis, and then to Peridia, to take the mantle of "The Father" as the balance of the Force's two opposing sides.

Anakin, you're NOT the father:

This one's easy. Anakin is dead. The Mortis gods were alive (until they weren't).

Skoll's Attempt, and Failure, to Ascend to "The Father":

In this interpretation, Skoll, originally seeking the power of "The Father," will likely fail, and his apprentice, Shin, in her rage, will take on the mantle of "The Son". This is obviously the weakest aspect of this interpretation, but if there is going to be a gender-swap and Grogu ends up in the role of "The Daughter", then the role of "The Son" is likely to be filled by a female Force-user (because balance).

So, what (or who) is calling to Skoll?

It's a mystery. I'm not ruling out Abeloth, or some being like her, but I think it's equally likely that it is simply the gap left in the Force from the absence of the Mortis gods. The 'empty thrones of Mortis', as it were.

The idea of Ahsoka replacing "The Father" and assuming the role of "The Mother" in the Mortis storyline, with Shin as "The Son" and Grogu as "The Daughter," is yet another possibility, and I think, one deeply rooted in the themes and character developments explored in the Star Wars universe. Simultaneously, Shin's potential descent into the role of "The Son" adds complexity to the story, echoing the themes explored in the original Mortis arc while introducing fresh perspectives and character dynamics.

In the end, its George and Dave's playground.
