And why Clara - the girl that the Doctor was searching for at the time - when she could have had any 'control freak'? Did Missy know that the Doctor wanted to find Clara? Or is it just the biggest co-incidence of all time that she delivered Clara to the man who was searching obsessively for her back in "The Bells of Saint John"?
I would also like to know if Clara remembers that the Doctor didn't find Gallifrey. All the other humans who awoke from the dream in "Last Christmas" appeared to have no memory of their dreams, so perhaps Clara doesn't remember the Doctor's admission that he didn't find Gallifrey?”
As far as 'Missy finding the one person the doctor was looking for' as far as I can see that's not co-incidence, it's a time loop. Missy chooses Clara for reasons unknown, she becomes his companion, then in name of the doctor is splintered across his timeline leading the doctor to encounter splinters of her earlier in his timeline which then leads him to look for her in the first place.
Basically the doctor was only looking for Clara because of an event that would happen when she already knew him, something Missy neither had a hand in or could control.
As such I believe that as far as we know, Missy's choice of Clara was nothing to do with the fact that the doctor was already looking for her, and since I don't think the impossible girl stuff is anything the writers are in a hurry to drag back up again, I doubt Missy's choice of her will have anything to do with all that.
I do agree that we should get some sort of explanation as to why she put them together though, more substantial than her just being a control freak, but based on Moffats past storylines where he finds more fun in the set up than actually putting effort into the resolution, or not even bothering to answer some things at all, I'm not exactly holding out too much hope/expectancy.
