So, let me get this straight...
A white knight is a motherforgeter that wants to defend the opposite gender (relative to situation), amirite?
So was Stocking ever in distress at any point? Because to me, she just sounds like a sadistic forget.
A white knight is a motherforgeter that wants to defend someone simply because of what they are, especially when it's completely irrelevant to the situation.
For example, teenage boys on the internet will sometimes white knight a girl who is being a massive rooster and sperging all over the place. They will defend her just because she's a girl.
Another example, let's say a TMNT fan posted a trap link to an animation of a spinning snake. A bunch of people will insult this person, rightfully, and other TMNT fans will stick up for him/her simply due to similar interests.
JUST EXAMPLES
And no to your last question. She was never in any distress. In fact, the white knights truly aren't even helping her. They aren't even giving her what she wants.
