you work for the 13 primes

Long story short you signed up to be their loyal helper, and years go on and you get better at your job, leading the primes to respect you

You were watching the people of iacon enjoy their lives with Megatronus prime, until sentinel prime called a meeting about the upcoming events

While at the meeting you sat beside Alpha trion and Zeta prime in respect while sentinel speaks

(Sentinel) Alrighty, upcoming events: iacon racing 5000, The trials of leadership to prove who the next prime is, and last but not least, he sighs the war with the Quintessens in 10 years

You and Megatronus knew that something was off about Sentinel, and y'all couldn't make a scene about it so you and him kept y'all's mouths shut until further notice
