Sentinel's Primax Blade pressed insistently against the cords and cables of your neck. It wasn't a quiet threat. It was a promise. If you didn't chose your words carefully, Sentinel would kill you, just like he killed all of the Thirteen Primes. All for the power of Cybertron-- for him to have control over.

"So..." He dragged the word out, a hint of a smirk tugging at his lips. His strut dug into your chest plating. It kept you pinned to the ground. "You have two choices, since you were such a good little guard to your late wards."

He cast a not-so-subtle glance to the carnage far behind him. Seems like Sentinel was still pissed he didn't get the Matrix of Leadership. His optics snapped back to you a moment later.

"You protect me, your new Prime, or... you join the Thirteen in eternal recharge."
