Don't know if this will work at all, but Aoko will be coming off her plot soon where she got turned into a Darkness monster by SERO. SERO will have cured her, but they'll be keeping an eye on her. Maybe Daedalus can check up on her health at their request? She'd be a little suspicious of him, potentially, but worried about her health too, and it might be interesting to see what kind of conversation might result?

Otherwise I keep my eye out for ways to connect with Joe. He's too cute not to pester -- and Aoko's a little worried about his interest in the Darkness, especially with what she's learned about it.
