The Warning message at the Temporal Loom Doors states the following: "DANGER: Temporal Radiation Levels escalate exponentially beyond this threshold. Likelihood of spaghettification increases 7000%. Proceed with caution."
In the TVA cafeteria there's a poster on the wall saying "Please keep breaks to 17 minutes."
Ouroboros is the concept of a snake eating its own tail that represents time as an eternal cycle of death and rebirth. Given that this series involves time travel, "Ouroboros", both the title and the character, hint that a time loop will be a feature of the season's storyline.
The center design of the doors to the Temporal Loom resemble the design of the doors to cerebro from the Fox X-men franchise. The doors even open the same way and use the same sound effects.
