I think it’s important to note the different treatment Seidou is applying to Akira and Amon.
When he was still an investigator, he admired them both. Akira was his rival and Amon his inspiration.
Now I think it’s a bit of the opposite.
After the ghoulification process, Amon became a rival because we know that Kanou’s goal was that of creating a perfect copy of Kaneki’s surgery. But Amon became a failed experiment, while Seidou was crowned like a success. Up until that moment, Seidou had always looked up at Amon, trying to get on his good side, offering him food, etc. Now, though, he thinks that their roles have reversed, because he calls Amon ‘a weakling’ and thinks he’s better than him.
The same role reversal happened with Akira, imho. When Seidou was an investigator, he always looked at her from the side. She was the rival, the one whose success he could never equal. The one he would never want to please. He always antagonized her, and took every chance to try and belittle her and her intuitions.
Now, though, he’s seeking for her approval. He wanted for her to look at him like an hero. Her betrayal hurt more than Houji’s - who was killed immediately, with no remorse, by an attack inflicted with his ghoul attributes. He wanted her recognition because he now unconsciously looks up at her more than at Amon.
So, keeping all of this in mind, I think that’s why he doesn’t appear to understand Amon’s words and seeks answers from Akira.
Right now, Amon’s voice must appear like his past self’s voice, the voice of the someone that wasn’t Good Enough.
At the same time, though, I think that it’s important that he’s asking Akira to explain. Right now Akira is the voice of the someone he wants to be.
Depending on which answer she’ll give, I think that Seidou will follow suit.
His salvation is in her hands because he himself put it there, imho.
*cups hands around mouth* SEIDOU TAKIZAWA LOVED AKIRA MADO AND SHE LOVED HIM BACK, AND JUST BECAUSE THEY HAD A RIVALRY SINCE THEIR ACADEMY DAYS DOES NOT MEAN THAT THEY AREN’T ALLOWED TO CARE, APPRECIATE, AND LOVE THE OTHER.
But what if Daichi had to work alone? What if Sugawara disappeared? What if he came back three years later as a Ghoul? What if he almost decapitated Daichi? What if he was killed right in front of Daichi? I'm sorry, I love your art.
