By The explosive ending to last night's Peaky Blinders episode, and Aunt Polly's last-minute intervention in particular, has taken up most of the post-match discussion on Twitter and Reddit.
But fan theorists reckon that the more subtly important moment came when Gina Gray, newly hitched to Michael, had a bit of a moment with Oswald Mosley.
But what kind of connection are we looking at here? There are a few competing theories, the first of which says that she's politically sympathetic to Mosley's proto-fascist cause. Now that we know Tommy Shelby's not particularly keen on all that and would prefer to put a stop to Mosley's manoeuvring, the theory runs that Gina is Mosley's insider, feeding information on the Shelbys to Mosley so he can destroy them before they destroy him.
Others say that there's a third point to this treacherous triangle: Al Capone.
That'd be a hell of a leap into a new territory for Peaky Blinders, and a fairly massive reach back into the past, but it's not entirely off the cards. Yet others reckon the betrayal goes even further, and that Gina and Mosley are a cosy fascist item.
That would grease up the already slightly slippery grip which Peaky Blinders has on the actual history of the time period, but it wouldn't be the first time an actual historical figure has banged a character in the show for plot purposes - Tommy slept with Jessie Eden, the communist organiser and strike-leader, to get hold of info about her communist mates last series.
