Rocky's behind-the-scenes documentary, Assembling: Making Rocky, allows fans to see how these behind-the-scenes workers made the series, as well as some of the concept maps that have been abandoned.
For example, when Loki entered the Time Mutation Authority, the queue was clearly empty, but in the early concept art, it was crowded with time criminals, including a little cute we are familiar with, Rocket Raccoon.

However, in an interview with The Direct, director Kate Herron said that the raccoon is not necessarily a rocket.
"That scene, you can't say that [only raccoons] are rockets."
"In the beginning, there were a lot of characters and characters in it, and we didn't know who those characters would be, we just thought, 'If a character could be an easter egg in a movie, or something from a comic, maybe it would be interesting.'" ”
"It's just that when the plan was going on, the COVID-19 pandemic came, and then after a 4-month shutdown, we looked at the scene and we couldn't shoot it safely."
No wonder there is no one in this scene in the episode, I think it is also to maintain a safe distance.
