Where’s Six? {Little Nightmares}
Throughout the Little Nightmares series, the infamous nine-year-old has appeared in the first three games, as a titular character in the LN and LN2 comics, and is occasionally presented as an Easter Egg in recent installments.
But since the timeline goes; VLN, LN2, Altered Echoes, LN, Descent To Nowhere, The Sounds of Nightmares, and LN3. It becomes easy to see she disappears at the end of the first game.
Lots of people assume she becomes the Lady and continues to run the Maw, but that couldn’t be farther from the truth.
Firstly, the duo in Little Nightmares 3 travel through a desert that could’ve been a ocean at one point.
Second, it’s not in Six’s character to be malicious. Sure, she’s occasionally cruel, but those choices were made in urgency. She was malnourished and wanted to get back to the surface. When she achieved the Lady’s powers, she killed the guests afterward (possibly more) before achieving her end goal of reaching the surface.
And after the game credits roll, she is seen standing plainly on the Maw. No dramatic actions like walking back inside. Even the Lady’s power looks invisible.
My guess is that killing and not succumbing to the Lady’s role had accidentally created a failsafe in the Nowhere. And since Six was the head of this failsafe, she got kicked out to neutralize - maybe even sanitize - the Maw.
It makes more sense why we don’t see her anywhere else in the future. Little Nightmares was OUR first adventure with her, but on her end, it was her last.
