I watch this show for Inko.
Though it was pretty clever of Inaho to rile her up to use her as a baseline. We also saw how much more of it is in him. It's a lot more than just a cyborg eye, they gave him brain replacement parts and additional processing power.
His personality is also changing a little. The old Inaho didn't seem like he would ever tease Inko like that. Rayet noticed what he was doing even if Inko didn't.
I'll also admit that I like the fake princess a little more this episode. Cliché as it may be, I do enjoy, "I'll steal everything from you!" characters. It shows the viewers more about the other characters. Slaine's already falling for it, even if he pines after Seylum in the tube, the Emperor was happy to see her alive at all that he doesn't bother looking harder, Inaho will already be disgusted by her, etc.
