No she doesn't.
She's been hurt twice in her career, and has folded immediately thereafter.
How is that heart? Surely someone should have to recover from being hurt and actually do something in retaliation before they could be considered as having heart?
If Honda has another fight, gets hurt, and then gets wiped out soon after again, are you still going to say she has heart?
Heart is not an inability to do anything whatsoever the minute you get stung with a punch dude. If you get punched and are then just waiting to get stopped, that ain't heart.
