The other zombies (mostly Grim's subordinates) still have their free will, meaning that in order to have the zombies do what the user (Grim) wants, they'll have to be told what to do and accept it. Luckily for Grim, he's a Vice Admiral, so they HAVE TO work for him, or they'll be in a lot of trouble. And that's not even going into account as to what Grim would do to them... >_>

So yeah, in other words, they just obey orders.
