CBS for aired Livewire out of order. It was created as the fifth episode:
Ep 4: "How Does She Do It"
Ep. 5: "Livewire"
CBS skipped episode 4. It's too soon for the network to be meddling with continuity. A series is fragile this early in its run, when each week builds crucially on the last. I remember when FOX murdered Firefly by (among other things) scrambling the episode order. Ever since, I'm sensitised to how television series suffer when networks shuffle episodes from the order that their showrunners intended.
With luck, CBS will air episode 4 in the fifth week, and nothing will be confuisng. With more luck, the network won't do this again for a long time.
