Because the initial airings of Best Wishes 1
and Best Wishes 2
did not have a Live Caster segment, the first time Best Wishes 3 aired, it used the segment from Best Wishes 1 rather than its standard segment. This presumably is because that segment introduces the Live Caster itself, and the writers wanted it to be the first to air.
