On September 2nd, it was announced that Alex Kingston will return to Doctor Who this Christmas as the time traveling, gun toting, Dalek killing archeologist, River Song.
For those who don't know, River first appeared in the two part episode "Silence in the Library"/"Forest of the Dead" from Series 4 (the fourth season of the new era of Doctor Who), where she died. But because of time travel, this was first time The Doctor met River, but the last time she met the Doctor, so they kept meeting out of order (so yes, "Wibbly Wobbly, Timey Wimey"). She then appeared in the Series 5 episodes "The Time of Angels" and "Flesh and Stone". It's later in the show where it's revealed that she is the daughter of then companions, Amy Pond and Rory Williams, and she was named after herself (it's complicated). She also married the Doctor, after she tried to kill the Doctor... but she didn't... which made all of time stop and everything combined... again, it's complicated.
And I'm a little excited to see River coming back. So far, we've seen River interact with two Doctors on screen. The Tenth Doctor (played by David Tennant) in Series 4, and the Eleventh Doctor (played by Matt Smith) in Series 5, 6, and 7, and I think it will be really interesting to see how River and Peter Capaldi's Doctor interact. But I do know that not everybody likes River Song. I can understand that, there are some Doctor Who characters I'm not too fond of (*cough* Rose Tyler *cough* The Tenth Doctor *cough* Martha Jones *cough*), but the episode could still be good.
And while it shouldn't be too surprising that River is returning because time travel and that her and the Doctor keep meeting out of order, I'd like to see other characters and companions come back. Classic Doctor Who companion, Sarah Jane Smith (played by the late Elisabeth Sladen) returned in the Series 2 episode, "School Reunion", and the Brigadier sort of appeared in the Series 8 finale "Dark Water"/"Death in Heaven". I say sort of because the original actor, Nicholas Courtney, died before he could appear in the new series and the character became a Cyberman (though he did make an appearance in the DW spinoff, The Sarah Jane Adventures). So here is my list of Doctor Who characters that should appear again in the show.
Susan Foreman (Carole Ann Ford)
Susan being the Doctor's granddaughter and first companion should definitely return. Her time as companion ended in "The Dalek Invasion of Earth" where she fell in love and the Doctor left her knowing she wouldn't leave on her own. She did appear again in the 20th Anniversary special, "The Five Doctors", "Dimensions in Time", and in the Big Finish Audio Dramas, but I feel she should appear on screen one last time.
Jamie McCrimmon (Frazer Hines)
Not only is he the most memorable companion of the Second Doctor and the first Scottish companion, but he has also appeared in more episodes of Doctor Who than any other companion. Jamie (and other companion Zoe) had his mind wiped of his adventures with the Doctor by the Time Lords in "The War Games" and was sent back to his own time period. Jamie did appear one more time in the Sixth Doctor story, "The Two Doctors" with the Second Doctor which created the theory of Season 6b, but that's a whole other thing. Jamie did return in the Big Finish Audio Dramas, but I think Frazer Hines should make some kind of appearance before it's too late.
Ace (Sophie Aldred)
Dorothy "Ace" McShane is the companion to the Seventh Doctor and all around badass. First appearing in the story "Dragonfire" as a waitress on the planet Svartos, Ace joined the Doctor and was the last companion of the Classic Era of Doctor Who. Not only was she awesome being able take on foes like Daleks with an rocket launcher and a cosmic baseball bat and Cybermen with a slingshot, she was a well written, complex character. She suffered from traumatic events as a child including having a bad relationship with her mother (which was really tough since she liked her mother as an infant before she knew it was her mother), her friend was killed by racists in a firebombing incident which led to Ace burning down an abandoned mansion, and was expelled from school for blowing up the art room as a "creative statement". She's the closest to modern companions. She's like Rose, but way better. Oh, and she's an explosives expert and makes her own explosives, Nitro-9. She's my favorite companion. And we saw her leave the Doctor. In the final story of the Classic Era, "Survival", we see her and the Doctor walk away to go on more adventures. But in the 1996 TV movie, we see the Seventh Doctor traveling alone. In the other forms of media outside of the show (comics, novels, and audios), Ace had more adventures with the Doctor. She was mentioned in the spinoff The Sarah Jane Adventures though. At the end of the 2 part episode "The Death of the Doctor" Sarah Jane says that she looked up some of the Doctor's other companions and mentioned that a Dorothy something was running an organization called "A Charitable Earth" (ACE). Though Sophie Aldred has said that she believes that it would not be Ace's chosen profession unless it was a cover for working for UNIT. I too would prefer that Ace's future was different. Preferably that the Doctor did take Ace to the Time Lord Accademy to become a Time Lord (which was hinted at happening with the Doctor testing Ace). Maybe she could be working for UNIT and come back since UNIT has been showing up more recently in the show. Or she did go to the Accademy on Gallifrey before it was time locked. I'd be happy with either one.
Captain Jack Harkness (John Barrowman)
Now I'm sure all New Who fans know about Jack, so I'll keep this one short. He first appeared in the 2 part "The Empty Child"/"The Doctor Dances" in Series 1 with the Ninth Doctor, and then appeared again is Series 3 with the Tenth Doctor. He was also the main character of the spinoff, "Torchwood" (which is an anagram for Doctor Who) that lasted 4 seasons, and will be in an upcoming Big Finish audio drama (audio dramas for everyone!). I think it would be cool to see Jack back interacting with the new Doctor and companion (and flirting with them). He was apparently supposed to appear in "A Good Man Goes to War" in Series 6, but that never happened.
Donna Noble (Catherine Tate), Wilfred Mott (Bernard Cribbins)
Now I put these two together because 1) they're family. 2) the two actors are really good together. 3) Donna can't do much because of the whole "her mind will burn, and she will die" thing. But I do have an idea for an episode with both of them. The Doctor and Clara (or some other companion) go and visit Wilf. They chat, swap war stories and adventures, and talk about how Donna is doing, then something happens, and the Doctor and Wilf go look around and see what's happening. Meanwhile, Clara goes around trying to keep Donna away from the madness to make sure that nothing triggers her memories of the Doctor returning. At the end, Donna manages to stop the monster/threat subconsciously and the Doctor and Clara leave knowing that Donna still somewhat remembers the Doctor.
So what do you think? Are you happy River's coming back? Should River even come back? Which characters do you want to return? Let me know.
