  • Sherloque implied that Thanksgiving doesn't exist on this Earth.[2]
  • According to Sherloque, there are no Zambonis present on Earth-221. During the winter, ice is cleared manually with squeegees. Winter also lasts for eight months of the year.[1]
    • This explains Sherloque stating, "I thought your Earth would be colder" along with the overcoat he initially wore upon arriving on Earth-1.[3]

Behind the scenes
