They're honestly probably my favorite bit of the game. We don't usually get an actual look inside the Doc's head; so these are amazing bits of lore that build his character. Like how he talks somewhat fondly of three of the four heroes in this game. Sonic, Amy, and Tails he all has some kind of genuine praise for, Knux doesn't get that. Least imo. He respects Sonic's speed and acomplisments, He respects how much Amy has grown as a person since Sonic CD, He respects and maybe faintly fears Tails' intellgence (based on his 'maybe its better he's wasting his potential in Sonic's shadow'). All Knux gets is 'He's a Rube, but occasionally useful if I can point him at Sonic.' Hell, Sage is the biggest thing. Seeing him actually get emotinally attached to one of his creations. Eggman's always had a little bit of a soft side in him, that usually comes out when he's forced to work with Sonic or any of his allies. But we get to see it on fully display here, and with the Audio logs added in we really see it evolve from "It is a useful program" to realizing he's starting to use She rather then It, to actually referring to her as his duaghter. This is probably the best look we've ever gotten at the kinda person Eggman is beyond evil genius, inside the games.
