Okay apparently there was a whole thing last year of someone talked to Chris Stack after seeing him Stereophonic and he said he was invited to film IWTV s3 in April, but he couldn't because of another project, which we now know is Stereophonic's West End run beginning in May. So multiple thoughts. For one, that seems to confirm at least some Nola flashbacks, since I doubt they'd only film one or two and have him be in one, though of course anything's possible. I figured there would be Nola flashbacks but it's cool to have some strong suggestion that there might be several. And maybe now he can do it! Since the filming would be happening when the show is running rather than in rehearsals. I also wonder if filming was initially supposed to BEGIN in April, or if it was beginning earlier and he was just being brought in in April? Maybe it suggests filming was supposed to start earlier, since if they film the episodes in order, you'd think Nola flashbacks might be in the second half of the season, at least. Plus there was what that person told you about Sam being on call to start filming by February, though I wonder if that was definitely to start filming or that he was on call to work on other things. If they were supposed to start filming in April, then April to June is not a big shooting difference. Though I guess even Feb 1 to early or mid-June isn't a HUGE difference, it's four months, so...who knows! And of course we don't REALLY know how long it takes them to make the show, they've never had a "normal" production season, so that doesn't tell us that much. Hmm.
