So I was thinking the reason Rex may of fell in love with the princess was not just beacuse she was pretty but more beacuse he ate the prince and Rex is getting some like brotherly love indigestion from the prince making Rex’s love more of a brothers love than anything and of course Rex wouldn’t have any idea about love between siblings as if sharkanoids are born like actual Earth sharks then Rex ate his brothers and sisters and the idea of siblings for Rex’s whole race would be foreign.
Brotherly Love Indigestion is a great name for a band
All I know is that any scene between Rex and the princess henceforth will (in my head) feature Lionel Richie’s Hello as the soundtrack.
