New clarity on a heartbreaking TBBT storyline — courtesy of its spin-off

Right, here we go — Stuart Fails to Save the Universe, the latest Big Bang Theory spin-off over on HBO, has lobbed in a fairly fascinating detail that could shift how we see Stuart entirely. The show is already full of returning faces and left-field twists about what happened to the TBBT gang after the original wrapped, but until now, it’s all been looking forward or sideways — not much in the way of proper character origins. That’s finally changed, though, thanks to episode 3.

Stuart Fails to Save...His Sanity?

First, the retcon that’s annoying a few fans: it seems like Stuart and Denise’s cute ending from the original series has been quietly rewritten. The new spin-off’s gone all sci-fi multiverse, so there’s still hope they’ll swerve back, but so far, it’s a bit 'wait, what?'. Anyway, onto the real bombshell — and yes, it’s not a massive storyline, more a quick offhand comment — but it tells us loads about why Stuart is, well, Stuart.

Deep in episode 3, we get this casual but telling exchange: Stuart says to Kripke that he’s not up for bailing out to any alternate universe unless Denise comes with him. The kicker — he admits his girlfriend has "a little problem with the sauce, so did [his] mum," and jokes that's probably what makes her so attractive to him. If there ever was a blink-and-you-miss-it line with bigger implications, this is it.

Stuart's aside in episode 3 reveals: his mother struggled with alcoholism, which he's now jokingly linking to his attraction to Denise.

Now, long-timers will know we don’t actually learn much about Mrs. Bloom (assuming that is her name, given the show’s not always careful with details). If you remember the seventh series of The Big Bang Theory — specifically "The Status Quo Combustion" — everything goes off the rails for Stuart when his precious comic book shop catches fire. By then, Stuart’s already living in the shop after a string of financial disasters. Yet, it’s never clear why he’s not staying with his parents if they’re alive (which we’re repeatedly told they are — Sheldon even checks in with him about it in series 5).

Stuart's Family: Strangely Absent

Oddly enough, when Stuart’s shop burns down, his own mum is apparently one of the first to accuse him of torching the place for insurance money — not exactly mother of the year behaviour. This all leads into one of TBBT’s weirdest subplots, with Stuart moving in with Mrs. Wolowitz after her accident. He winds up basically acting as her live-in carer (and housemate), and eventually she even stumps up the cash to help Stuart re-open the shop — which sparks a minor feud with Howard that the show promptly forgets the second tragedy strikes.

And yet through all this, Stuart’s actual family barely get a mention. Were they around and just useless, or was that sidestepped for sitcom convenience? Now, with the fresh bombshell about his mum’s drinking, it suddenly clicks. Maybe she offered help and he turned it down, or maybe she just wasn’t able to be there at all. Either way, the man’s been on his own for ages, and the show’s finally let a bit of truth slip through in typically awkward, darkly comic fashion.

• Stuart never appears in season 1 of the original Big Bang Theory
• He rarely talks about his personal past, apart from the odd art school anecdote (usually with a side order of crippling self-doubt)
• When things go wrong — as they seem to do for him more than anyone else — he simply carries on, battered but still moving

Alcoholism’s obviously a serious topic, and to their credit, even this throwaway line in the spin-off isn’t played purely for laughs. If it turns out Stuart really was raised by an alcoholic mum, it goes a fair way to explaining his knack for bouncing back from disaster, the social awkwardness, and all those layers of sad clown self-deprecation we’ve come to expect. The hope now is the new show doesn’t just leave it there, but finally fleshes out the man who’s spent most of his on-screen life as a bit of a punchline.
