How is Dave shown serving?

The usage of the word ‘Serve’ is not arbitrary, Dave is heavily tied to Serving, as the literal Server for Rose and Jade, and also aiding them in everything he can- Serving Rose a Map of the Furthest Ring through his knowledge of Time, Serving Jade in her endeavor to gather the Frogs, Serving Terezi money that he’s gathered through his Time Loops. Literally spending Time and using his Time Powers to Serve everyone. Similarly, Pages being tied to the Butler Island joke as well, makes the Knight-Page pair obvious, and the most likely intended purpose for them to be ‘Serving’, ‘Aiding’ and ‘Giving’.
