Gravemind has his own agenda. Aside from what the arbiter and master chief agree on, we know they both want the "sacred icon". The arbiter wants it for the great journey, and the master chief wants it to stop the activation of the rings. Neither of them have any input on what gravemind says, or does, and since his agenda falls parallel to that of the master chief and arbiters, he takes advantage of them, knowing that they will see it as an opportunity to fulfill their own agendas, yet still doing the deeds of the gravemind and not realizing it.
It is unclear what gravemind's agenda is. Everyone is speculating on what his agenda is, but in my opinion I don't think there is an agenda as much as a question of "why he sent them" to try to retrieve the icon and stop the prophets.
The point being? If gravemind really want the master chief to stop the prophets and obtain the key, then why would he have sent the arbiter? If at any reason, I'd say gravemind atleast sent the arbiter to better show him the truth behind the prophets and the brutes, as we know that gravemind has one prophet, and one oracle in his possession.
Not anything to go by, but these are my thoughts on the matter.
