However, time only passes differently in some realms, not all. In the Realm of Oni and Dragons, it was clearly passing the same way it does in Ninjago. The same goes for the UnderWorld, the Realm of Madness, the Cloud Kingdom, and Chima. Some of the Sky Pirates could have been in a different time realm, but at least some of them had different reasons.

True, for Dogshank, Doubloon, and Monkey Wretch it could also be, because of their mutations, but for Flintlocke it was definitely because of time passing differently in the realm he was in, as he is just a normal human.
