In Star Wars Episode II: Attack of the Clones Senator Padme Amidala falls out of a clone Low Altitude Assault Transport (LAAT) ship during the Battle of Geonosis. Anakin, of course, wants the ship to land so he can stay with her. Obi-wan then reminds him to “do his duty” and help him kill Count Dooku.
However, Anakin's standing orders and “first priority” from when he and Padme were on Tatooine were to protect the senator at all costs:
Mace: [to Anakin] Anakin, we will deal with Count Dooku; the most important thing for you is to stay where you are. Protect the Senator at all costs. That is your first priority.
Anakin: Understood, Master.
So, why didn’t Anakin argue that when Obi-wan told him to come with him?
