This year’s Doctor Who Christmas special is a big one. Not only is it a festive delight with appearances from Mark Gatiss and David Bradley playing the First Doctor, but it’s Peter Capaldi’s last trip in the Tardis before he hands over to Jodie Whittaker.

Excitement is at fever pitch – but details of exactly what to expect from the episode have been kept closely under wraps. That is, until now…

There was a lot of love for the exchanges between the First and Twelfth Doctors.

"Do I become you?" This bit. Twelve has been around the universe for a long time while his 1st incarnation is just getting started on that same journey. Both were so endearing here; it made me smile and tear up. 💕#DoctorWho #PeterCapaldi @bradders_david @BBCCiN #TwiceUponATime pic.twitter.com/hhVlaT62Y4

"Always remember where you parked. It's gonna come up a lot." 😄 Based on this clip, the Christmas Special may very well be glorious. #DoctorWho https://t.co/1r4lqMJGZB

While the World War I reference left some feeling rather emotional.

"World War One?"
"Judging by the uniform, yes."
"Yes, but what do you mean… One?"

Beautifully painful moment, #DoctorWho

There was the odd tweeter who wasn’t so sure…

Mainly because the appearance of Bradley elicited traumatic flashbacks…

Every time I see David Bradley as the Doctor, I suddenly have traumatic flashbacks of Game of Thrones #DoctorWho pic.twitter.com/ZHTnbLu2m2

But while the love for Peter Capaldi knows no limits:

DID NOT REALIZE HOW MUCH I WAS MISSING CAPALDI. Cannot wait! #DoctorWho https://t.co/E3CgSUhqP0

Christmas can only mean one thing. Pass the tissues…

“I *AM* younger!!” Oh, Peter Capaldi, I’m going to miss you so. #DoctorWho #PeterCapaldi #CIN2017 https://t.co/xWK4cyoKC9
