You could try replaying the mission from the i Droid menu in the helicopter. This time DON'T KILL HER AGAIN! She's a rich character despite the childish portrayal that Kojima gave her. Also, I LIKE her design. *Grinning shyly*
And if the lack of clothes makes you uncomfortable, just do like me and buy her XOF outfit which is full stealth battle fatigues. I don't really mind her clothing choice TBH. ?
