First of all, if you're not caught up on Stranger Things 2, then this is your chance to turn back.
Alright, so by now we are all familiar with the character Kali, who was later revealed to be Eleven's long-lost "sister".
But there's an interesting connection between the character's name and the significance it has in Hindu mythology.
In Hinduism, Kali is known as the goddess of time, doomsday, and death. She is also referred to as an "eradicator of evils", and is seen as a fearsome figure of strength who deals with the destructive side of justice.
In Stranger Things 2, Kali follows a similar mission where she uses her reality-altering powers to seek revenge on the men who have wronged her.
The Hindu goddess is also linked to being a gentle and ever-caring mother.
This can be compared to Kali's motherlike interactions with Eleven in the episode "The Lost Sister".
Although her punk-like appearance would suggest otherwise, Kali shows a gentler, more caring side to Eleven, choosing to immediately embrace and care for her.
And like a mother, or even an older sibling, Kali also takes Eleven under her wing and teaches her how to better harness her psychokinetic abilities.
Plus, considering how much the Duffer brothers love their '80s movie references, there could be another link to Kali found in the plot of Indiana Jones and the the Temple of Doom.
Released in 1984, which interestingly is the same year that Stranger Things 2 is set in, the film follows Dr Jones tracking down the Thuggee cult, who worship none other than the Hindu goddess Kali.
Even if this turns out not to be true, Kali is a badass and we can't wait to see more of her in Season 3.
