Two weeks on, and plenty of us are still chewing over the events of Doctor Who's mid-season finale The Angels Take Manhattan – aka A Pond Farewell. Amy and Rory bid goodbye to The Doctor; zapped back to a point in fixed time from which they could never escape. Of course, I still don't understand why they couldn't just visit him in Washington, but that's one of Doctor Who's great Questions You're Not Supposed To Ask.

Less satisfactory about this saddest of happy endings was the question: what about Brian? We only met Rory's Dad this year but he instantly became beloved. Was Brian not the ultimate loser here? Amy and River went to all the trouble of writing that postscript for the Doctor, but Brian, we were supposed to believe, was just left to water plants, waiting endlessly for the return visit that would never come. Paradox or no paradox, that's some callous storytelling.

But it turns out that Moffat and co did consider this. And today the BBC website reveals another epilogue to the Ponds' tale. The lovely scene above was written by Chris Chibnall (who penned both of Brian's episodes) but never filmed. Now, using storyboard animation and a voiceover from Arthur Darvill, we can see how Rory told his dad that he and Amy were OK.

Cute, isn't it? The Ponds got to be parents after all – was anyone else scrambling their heads around timelines, working out whether that illustrated child could be baby Melody? – and Rory makes ultimate peace with his Dad by buying a trowel.

Of course it's still a bittersweet ending for Brian. Even if I had a son, I'm not sure the knowledge that he lived long and well in the coolest city on Earth would make up for never seeing him again – he would have had to live through the second world war for a start. The zapping back in time of loved ones is a new range of emotions for all of us, but Brian was always an understanding fellow.

As a fan, it's really lovely to see this scene – particularly given the rather mixed reactions to the Ponds' farewell. So should it have been filmed? Would you have liked this final explanation to have been tacked on to the episode? I'm not sure. It would have made for a long, overwrought ending typical of the Russell T Davies era, and part of the thrill of this departure was the quick, accidental pointlessness of it all.

Some commenters on our blog have said that Darvill was robbed of a big final scene. This addresses that to some extent, but I would still suggest that the poetry of this whole arc was in the story of Amelia Pond, the Girl Who Waited. And I don't care that she's not real – I'm glad she's happy. More to the point, perhaps this clip opens us up to a whole new spinoff about two old codgers, Brian and his grandson Anthony, seeing off extra-terrestrial menace in suburbia, just like Sarah-Jane.

But what about you? Did this emotional little postscript tug on your heartstrings one last time? Or are some things better left to the imagination?
