As for 'complex' companions: I've never seen one in Doctor Who and never expect to.
You may have read that in a novel somewhere, or in an audio story or just made it up in your own head :P Nothing like that has ever been suggested in the show, which is the only canonical source in Doctor Who. As far as the show has ever intimated she is is his natural granddaughter.”
Rose was complex. She was fiesty, yet a little awkard at times, she had a real home life situation in which she had issue's and had experienced loss, she was independent and yet totally reluctant to leave the doctor's side, she was cool and yet a bit of a chav. You couldn't really say oh, yeah that's just your basic character template, because if you watched it properly, the character's motives and emotion's appeared so deep.
That's my opinion but even if people dont agree,
I'm sure that there are many that could make the case for many other companion's being complex(from what I've seen, i'd say sarah jane smith was also), so for you to say you have never seen a complex companion, i'd have to guess you've never connected with a companion enough to notice.
