Even following the filming pics, you don't see everything. Some of the filming is done behind closed doors, some of it in studio (green screen). In either of these cases, you probably would not know who's in a scene until at least Promo Pics (where ABC releases some of studio shots) are released. That is usually Tuesday or Wednesday the week leading up to the airing.
