Well, one random thought and one grumpy one.
Random: All of Martha's conversation in the last episode about her family being put in danger because of her relationship to the Doctor reminded me that she still doesn't know about Adeola... I can't help thinking that this would actually be kind of an awesome moment for Ten and Martha, if they were willing to go there. After all, Martha probably knows where her cousin really worked now that she's in UNIT and has worked with current Torchwood. It would be something big enough to get them out of their current impasse, perhaps. And speaking of which...
Grumpy: I sort of wish I had a time machine, to be able to go back to people who were asking what more the Doctor could have or should have said to Martha as she was leaving the TARDIS (because "you saved the world" and "thank you" should have been enough, how could she be entitled to more than that?), show them the false goodbye between him and Donna in TSS, and say, "Well, something like that, for starters..." It still, still bothers me that Martha, who saved his life literally as well as figuratively for a whole season, still thinks that the Doctor's opinion of her is so low that he just replaced her without a thought--and that when Donna insists that he said good things about her, can only, apparently, think of the embarrassing things he must have said about her feelings for him. And it rankles that Donna gets the open, easy acknowledgment after only three episodes (two and a half, really, since it takes them so long to meet up in PiC), and Martha got a statement of fact about her accomplishments and a thank you. That's not to take anything away from Donna...but it makes Martha's treatment, the omission of such a moment, even more glaring. I know I'm supposed to think that the Doctor's learned from what happened with Martha and can now make the open, easy acknowledgment he couldn't do with her, but when he's right back to pulling away from Martha in the very same episode in which he's praising Donna...it just irritated me. I know it was supposed to be a joke and all, but I didn't find it at all funny--not when that moment still needs to happen between the Doctor and Martha. Maybe that means I'm a humorless grump, but then I guess I'm a humorless grump.
And I realize that we're not done with this arc, so I'm still holding out hope that this will be addressed...but not a lot of hope, it has to be said. I'd love to be proven wrong, though.
