I honestly could just tell from the start what he was doing considering it was a directly follow up on the last episode, you say exactly what happened beforehand, you've seen Clara do the bluff before, and you know she's both good at it and has fun doing it...
Plus I
may have missed the fact they added her face to the Intro.
But yea, I totally get how she's turning into the Doctor personality wise. I just didn't ever think she was a literal time lord in disguise.
(And now I have the transformers theme playing in my head, only the lyrics are "Companions, Time Lords in disguise", which kind of does work for Donna at least
).
Except the for the "Both are terrifying when angry" thing. Maybe I just don't get freaked out or intimidated easily but I can't remember a time when I'd call them terrifying. Definitely moments when they had some emotional breakdown (which are the moments I assume you're talking about) but not terrifying.
But yea, her constant lying is worrying. Especially when you consider that companions of the doctor have a history of bad things happening to them, not necessarily end unhappy or miserable mind you, but concerning none the less...
Rose & Mickey= Stuck in another Universe, but considering the people with she's probably the best off of so far.
Captain Jack = Given his previous experience before the Doctor he was probably good at coping with a lot. But he had to deal with being unable to ever die while watching everyone he knows die, and being thrown into an unknown time out of the blue, and have no idea about how his immortality happened for a while because he was basically abandoned by the Doctor.
And having watched a season of Torchwood, he is definitely a lot more cruel and calculating (though still a good person and the same Jack whovians know and love) when the Doctor isn't around. Which granted is pretty confirmed not to be the doctors fault, just that Jack puts up an act around the Doctor so he doesn't have to see that side of him, but he clearly doesn't just brush things off easily like the show might have you think.
Martha = Least damaged in terms of what directly happened, but also least good on top (Like how Rose found her dad and a proxy doctor) but her life still clearly impacted by being rejected by the doctor and having her eyes opened to the dangers of the universe,
Donna = Memory wipe, and her parents have to be extremely careful not to say anything to reminder her of what was wipe or they'd kill her.
Amy & Rory= Stuck back in time. Still happy mind you cause Rory, but they still got separated from everyone else they knew and would have had to deal with a lot of technology and social norms they were used to no longer existing.
River = Has to deal with seeing the love of her life slowly forgetting who she even is until ultimately he doesn't recognize her at all.
