This is how Twilight's promotion, Twilight's secret assignment, and Zeta leaves to help out the Xenomorphs goes in My Little Pony Transformers: Revenge of the Sith.
[We then see Twilight standing at the center of the Council Room]
Ventus: Twilight Sparkle, this Council does grant the Senate's request to make you a member of the Jedi Keyblade Council.
Twilight Sparkle: Thank you, Master Ventus.
Ventus: We do not, however, grant you the title of Master.
Twilight Sparkle: What?
[Nighlock looks at Anakin for help]
Twilight Sparkle: How can you do this? This is outrageous. It's unfair. How can you be on the council and not be a master?
Ventus: Take a seat, Master Sparkle.
Twilight Sparkle: Forgive me master.
[She sits down]
Terra: We still haven't found Grievous.
Zeta Prime: Grievous is hiding out in the Outer Rim.
Ryan F-Freeman: Finding him is top priority.
Terra: What about the attack on the Xenomorphs?
Ventus: Yes, for those of you who are not aware, the Xenomorphs are apparently being attacked by the enemy and sent a distress beacon.
Ryan F-Freeman: We need to send someone.
Zeta Prime: I will go. I have good relations with the Xenomorphs.
Ventus: Then it's decided. Zeta Prime will help the Xenomorphs. Council adjourned.
[The Council got up and left]
[We then see Ryan and Twilight walking in the hall]
Twilight Sparkle: I don't get it. How could they put me on the Council and not even make me a master.
Ryan F-Freeman: Come now Twilight. You've been given a great honor. To be on the council at your age. It's never happened before.
