While Anakin was being seduced, the other Council members were discussing whether they should take any action regarding Anakin's obvious relationship with Senator Naberrie. Obi-Wan pointed out Anakin's delicate state of mind, and anymore discipline might make him worthless as a spy on the Chancellor.
Knowing Anakin was gone, Obi-Wan visited Padmé. He hoped for a little comfort before he left on his mission. The Force gave him warnings that something bad was going to happen on Utapau, and he wanted to see Padmé one last time in case the event was his death. He kept the conversation on Anakin, so that she wouldn't get suspicious and ask him to leave.
Some things she said were very curious, and a little seed of suspicion was planted. He shook it away, sure that not even Anakin would stoop to that level.
Just before he left for Utapau, Anakin saw him on the flight deck.
Anakin almost choked on his words as he apologized for arrogance and pride to Obi-Wan, to regain his trust after his outburst defending the Chancellor.
He was incensed when he came home to Padmé and she was bubbling with happiness.
"Obi-Wan has been here, hasn't he?" He recalled in his dream, Obi-Wan had been comforting Padmé, while he had been absent. Jealousy raged, and he began to suspect that Obi-Wan had been her former interest.
"Yes, he's worried about you and wanted to let me know that you might be stressed from all the business with the Council and the Chancellor. I told him you'd been having nightmares."
"He doesn't have to worry about me anymore. I'm not his Padawan. Everything's going to be fine. I promise nothing will happen to you."
Padmé felt shivers as he said that. As her babies had grown, she'd started to develop a sixth sense. She'd realized that because her children were Force-sensitive, she was feeling the Force through them. And there was something ominous about Anakin, right now.
That evening, her babies warned her something was very wrong at the Senate. She could almost see dark clouds of the Force gathering into a vortex of doom around the building. Something was about to happen. She worried for the next hour, and then, at the Temple, she could see fires and laser blasts. It was under attack.
While the Temple still burned, Anakin returned.
"Anakin, I was so worried! The Temple's under attack!"
"I told you, everything's going to be okay, now. The Jedi tried to take over the Republic. Master Windu tried to assassinate the Chancellor, but I stopped him. What's happening at the Temple is just retribution. The Jedis won't hurt anyone else, ever again."
"What are you talking about? The Jedi are the protectors of the Republic, they would never try to overthrow the Chancellor, unless he was doing something wrong."
"And I'm telling you, I saw Master Windu try to kill the Chancellor. A real Jedi would have arrested him."
"What's going to happen to the rest of the Jedi? What will happen to Obi-Wan?"
"I am so sick of hearing about Obi-Wan! You are mine, now!"
"I am yours now." Vader was so used to using suggestion on her that he'd done it without thinking.
"I'm going to Mustafar to finish the Separatists. When I return, you will take your place at my side, and you will never speak the name 'Obi-Wan' again."
