I think they are putting it there, because legends fans like us, will wake up or tape the show in that time slot.
Mmm ratings.
If it says Legends Of The Hidden Temple at 7:30 EST, I'd trust it.
Off topic, notice how under the name of the show, it has the episode name. It counts down from 340K, to 337 K on Thursday, and jumps to 336J on Friday.
What do you think that means?
