First of all, I'm finally, finally, FINALLY caught up on Doctor Who. I just watched my first-ever newly aired episode, "Closing Time", this weekend. Unfamiliar sensations!
Second of all, I've got some Doctor Who thoughts to post, and I shan't stop until they're all gone. Here's a sampler: I don't think the Doctor has any reason to feel guilty about screwing up the lives of his past Companions, which has been a major theme this season.
Yes, bad things happened to the Companions in-episode or in-season, which is fine. But that's more than counterbalanced by the wonders the Doctor shows each of them when roaming across the universe. And honestly, I think almost all of them are better off for their time with the Doctor, so I don't see why he's whingeing about screwing up their lives.
Look at the Companions we’ve seen so far: Rose, Mickey and Rose’s mum are happy, and Rose has her own Doctor, which is what she’s always wanted. Sure, they’re in an alternate universe and sure, Rose had to give up everything else in our universe to gain what she has, but she gained her dad back as well and it’s not like she ever seemed to particularly care about anything besides family. Martha’s having the time of her life, having been elevated from a lowly doctor’s assistant to Companion and then to UNIT VIP, before leaving them to run around blowing things up (in "The End of Time"). She’s married, in love and clearly happy, even if she’s not on the TARDIS. And Donna, while she’s suffered the greatest loss of any Companion, is also oblivious to it! For Donna, her life is exactly the same as it was pre-Doctor. She’s neutral.
Obviously we've yet to see what happens to Amy and Rory, but for now, I think it's safe to say that the Doctor shouldn't feel guilty about his past Companions.
