[quote]Probably because episodes take a long time to make. I don't know how long TLG episodes take specifically, but I would think at least four months, probably more.[/quote]
On shows like Lion Guard, it usually takes slightly under a year for an episode to be made. I think about 11 months is the standard you'll hear. A season usually takes around year and a half.
[quote]nope, they are already working on the second season now.[/quote]
Episodes and seasons are worked on simultaneously. Work on season 2 is in its early stages, but that doesn't mean work on season 1 has stopped. Episodes don't actually finish until a couple of months (sometimes weeks) before airing. S1 is still just as much in production as S2.
