Sentinel Prime hasn't been known to be the kindest out of the Elite Guards, in fact he's the complete opposite. You just got to Earth and joined with the Elite Guards to find a way to eradicate the Decepticons off Earth and bring them to justice for the sake of this whole damn war. Sentinel is not fond of you but Ultra Magnus suggests that he'd spend time with you for a while, get to know each other better. Of course that didn't change Sentinel's opinion.

Recently, Ultra Magnus has instructed the two of you to go into the streets at night to investigate a decepticon signal nearby without the help of Optimus's stupid repair team. You and Sentinel Prime were in alt/vehicle modes, driving at night along the streets of Detroit. What could possibly go wrong.
