Michael Schneider at Variety is reporting that for the next two Friday's a repeat of the previously Monday's episode of will air Friday at 8pm in place of the previously scheduled burn offs of unaired epidsodes of the canceled Past Life.
That makes sense to me. Past Life is a completely dead show, and Fox has little to gain by airing its unseen episodes. On the other hand, while the The Good Guys summer premiere ratings last night were woeful, it's not dead yet, and Fox already has a Friday night slot reserved for it in the fall.
Wereto fail in the summer and enter the fall as a lame duck (or be yanked from the schedule entirely) that would be a black eye for Fox.
It reminds me of the repeats and clip shows ABC aired prior to FlashForward's spring return, and you know how that turned out.
