I think that, like most people, she various aspects to her personality. There may be certain things she's 'hard as nails' about and other things about which she's very sensitive.
From her long conversation with Jenna on live feed it seems she's a fighter (as in martial arts and boxing) and obviously quite tough in many ways. It doesn't mean she doesn't also have a sensitive side.
I'm tough when it comes to some of the things going on in my life, I have to be, which can come over as unemotional but are just me being stoic and getting on with things, but I can be very sensitive about other things.
I imagine we are all like that. We don't just have one emotion, there are many sides to all of us.
