But in America, they didn't replace those two slots, they just showed the 24 episodes and had a break until third season. And those two episodes in America were shown mid-way through Season 3, not even at the beginning... so they have an uncertain status, because they are considered part of Season 2 (in terms of production order and plot order), but it doesn't sound like they are being included in the screening of Season 2 anywhere.
The interesting thing will be if the Australian DVDs have them included or not... when they get up to that volume later in the year.
