After an hour-and-a-half pondering over another cryptic emoji post, the BBC has revealed that David Tennant and Catherine Tate will be back for Doctor Who's 60th Anniversary celebrations. They will return in 2023 for "the battle of a lifetime".
However, can we say this is the Tenth Doctor and Donna? The return has been a big reveal, but a big reveal shrouded in mystery. When we last saw these two, back in 2008-2010, the Doctor was forced to tragically wipe Donna's mind in order to save her life, but more on that later.
The reveal teases the nature and placement of their return going in all kinds of directions.
RTD himself has said: "They're back! And it looks impossible - first, we announce a new Doctor, and then an old Doctor, along with the wonderful Donna, what on earth is happening? Maybe this is a missing story. Or a parallel world. Or a dream, or a trick, or a flashback."
So that certainly gives us a lot to think about...
With that, here are eight ways the Tenth Doctor and Donna could return to Doctor Who.
8. Back To Series 4?
Starting with the straightforward idea, similar to novel or Big Finish appearances, we could pick up with the Doctor and Donna midway through their Series 4 travels.
The easiest choice would be to pluck these two from their later travels in the series, so that they've gelled and got a bit of travelling under their belt, picking up from there. Could an adventure they've been on effect the story of the 60th? Will they be brought from Series 4 to the beginning of the 14th to meet up with the new Doctor? Time will tell.
Tennant and Tate's one series on the show is arguably the most highly regards of New Who. The two of them have irresistible chemistry and it is hoped this magic is recaptured again for their return. But with Russell at the helm, they couldn't be in safer hands.
It is still unclear how the Doctor and Donna are returning for the celebrations, but in terms of timeline placement for the two of them, this is the least complicated choice.
However this happens, fans will be over the moon to see these two again.
