Yes... in a sense

Sae crossed her arms. She did generally trust Makoto and her friends. They had saved the world after all. And more than that, they had saved her personally. She also felt that she did owe Futaba to some extent. She felt terribly about how she had treated her and Sojiro before, even though both had said they had forgiven her. But just like she still had her lingering guilt, she always felt like Futaba still had some lingering resentment.

Sae looked to Makoto.

"Makoto... Have you been hypnotized?" She asked.

Thanks to her programming, Makoto subconsciously that her role was to convince Sae to let Futaba hypnotize her. And she could hear the skepticism in her voice.

"Not yet, no. She had brought it up to me last night but I was busy with school work." She lied, although very naturally. Futaba had heard that Makoto wasn't exactly the best at subterfuge from Ren and Ryuji before. She had either been practicing, or the hypnosis had helped. Either way, Sae seemed to believe her sister.

"Fine. Futaba, I will allow you to try to hypnotize me. However, Makoto, I need you to keep a watch over me the entire time." She said.

Futaba was slightly hurt that Sae didn't trust her. Granted she did plan to enslave her and turn her into a humiliation guinea pig, but there's no way Sae could know that.

Even so, Sae sat down on the couch - her powerful aura, her tall, slender, sexy body still covered by her usual suit, Futaba desperately wanted to see her without it.

So she got to work, with Makoto and Kawakami watching.
