No, not Isa! She looks like a little girl...
Yaiceca, naked, or in the process of being stripped down, with Justice sat on top of her, pinning her down with his knees on her arms, wearing a T-shirt that says "Justice is served", and holding a sign in his hands with a generic picture of a man and woman and the word "TERRAN" in large letters, or just "TERRAN" with no pictures, and the JGASF in the background cheering him on! He would obviously be showing her the sign, and trying to get her to say it.
If you feel it would break Justice's character to do that, substitute him for someone else. I'm thinking more along the lines of "say it, or we're taking more of your clothes off" here, rather than rape. So one of the girls would do. I just picked Justice because of the name. Tempest might be the best choice. I think she'd enjoy it.
(I should point out I really don't like Yaiceca, but I wouldn't do that to her if it was real. But if someone's getting stripped down, let it be her!
