Really, the songs too? That is unexpectedly nice. [ Despite Peter's general wariness with having people in his head or reading his thoughts -Thanks, Ego,  go fuck yourself - he doesn't mind of it when it's Blue doing it. ]

Pinocchio, the movie I watched, that's it,  has one of the sweetest songs I ever heard. I really liked that film as a kid, and my mom sometimes  sang some of the music while doing things around the house. 

[ Since it's a memory he has clearly, it's not hard to start humming the song 'When you wish upon a star'. If what Blue said it's true, and his psionics work for a bit, he might catch the full song, sung in a woman's voice. ]
