At one point while talking to Suzy it sounds like Antillamon says, "Don't get cawwied away." Did the voice actress forget she wasn't playing a child?
Antillamon is the guardian of the South Gate, which indicates that there is more than one gate. Since Makuromon & Caturomon weren't shown guarding any other gate & the other (original) Devas are dead, who are the other guards of the other gates? And who will be the new guard of the South Gate?
It'd be pretty hard to say at this point, seeing that we know pretty much nothing about what the heck these gates are...
Lopmon was just immitating Suzie when she said "Cawwied Away".
Why did the Sovereign to decide to waste a Deva on guarding a gate? Shouldn’t Antillomon have more important things to do? On the other hand, if guarding the land of the Sovereign is so important, why don’t the other gates have Devas guarding them?
Maybe other Devas had been guarding the other gates until they were sent to the real world. I guess the bird Sovereign was so stuck up, he made sure his guard would be the last one to be sent.
Heh, that sounds like ol' Zhuqiaomon, all right.
