Doctor Who: 8 Ways The Tenth Doctor And Donna Could Return

Alternatively, still keeping within the timeline of their adventures, what if we meet the Tenth Doctor and Donna during the Tennant specials era. Although that runs the risk of seriously hurting us fans...

If you're on the Doctor Donna hype train, you know how their story ends. But I'll remind you anyway.

When we last saw these two, the Doctor is forced to wipe Donna's memory of all their adventures, in order to save her after taking on the mind of a Time Lord. However, when taking her back home he reveals that if she were to remember then her mind would burn up.

This is actually one of the options the BBC teases. The press release states: "He left her family with a warning: if ever she remembers, she will die. But with the two coming face to face once more, the big question is, just what brings the Doctor and Donna back together?"

This is one of the more interesting options to take, as it allows for serious continuity expansion. This is a dark period for the Tenth Doctor, and to be back with his best friend after all the tragedy would be heartwarming. Who knows what Russell could pull out from after this tragic end.
