I put up with this behaviour by telling myself that he's only sixteen and, besides, in a few years be living somewhere else(1). I don't blame writers and producers for wanting to have wham episodes but like much in television these days it seems to have become a requirement rather than a joy. The problem is that the real appeal of a TV series(2) is spending quality time with fictional characters you like. This involves building a consensus reality that the viewer can slip into once a week with an expectation that they're going to get more of the same.
A wham episode by definition blows this all to shit so that you spend the summer wondering what the fudge is going to happen next. That's one source of dissapointment but now the consensus has been shattered it means that the primary role of the season opener is to recreate that consensus - everything else, story, character and plausibility are secondary. This is why they often feel unsatisfactory.
Sometimes that have to spend two episodes putting humpty dumpty back together(3) which just doubles the tedium. So please, for the love of god, can we skip the wham episode this season.
(1) No doubt I will be sad and lonesome without him but at least I'll be able to fast forward through the dull bits of season openers.
(2) British TV hardly ever makes proper TV series any more so the art form is mainly confined to the US and, oddly, Denmark.
(3) Often taking the opportunity to remove any troublesomely popular POC characters and replace with them with skinny redheads.
