There's a long pause as Idia leads the way down the pathway towards the large building in the distance, turning over what Yondu just said, and deciding... yeah, why not? He may be able to offer something. Not answers, but... more questions to be asked. "I think something went wrong... or they didn't tell us everything when they sent us back. We're not really us."

Yondu's also spot on about Idia. He hates attention, but really did well under positive attention. Compliments at his achievements. It inspired him to work harder and do better. If he believes them and didn't think they were just mocking him... So his 'their loss' keeps Idia quiet for awhile, before letting out the lightest of 'heh' as a laugh. Yeah... he may not had done much at the school, but he was still brilliant. He would be a missed asset... just... most wouldn't realize it.

"Ah," Yes, he had left that hanging out there for follow up, hadn't he? "I knew this was coming. Once I had left this school my existence would be wiped from it. Everyone would be made to forget me. It's part of my responsibilities for the future of my family business." It's... weird to talk about it to someone outside of STYX. It went against everything the organization was about. This would be a massive breech of security.
