@Akera93 I'm all for it, on the other hand. Imo, when else should she basically have a breakdown than at the sight of (someone who looks like) the one man she dearly loved back in her past life. Mind you, the whole reincarnation-and-knowing-your-past-life is enough of a mindfuck as it is, but then we've all seen what a rollercoaster of a past life she's had.
She's definitely the stubborn and strong minded type to bottle up most of her emotions, try to remain rational, and keep cool as much as possible, and we've already seen so much of that. Most of the time she remains this way, but it just takes one small/specific thing that could connect to whatever she holds dear or means something for all her emotions to spill out, and because she often withholds a lot of herself, the amount and degree of all that pent up energy is intense albeit rare.
I appreciate this side of her because it makes her more human, indeed. Yes, she's a badass, and yes, she kicks ass. She's often unphased by all the bullshit and assholery around her which is something I wish I could emulate at least 1/4 of. But I think her vulnerability does not detract from any of that at all. Rather, it only reinforces her inner strength.
