Bee

Ironhide. He hates how you two are so close.

Sam

Optimus. He's an extraterrestrial leader, smarter than him, not to mention taller.

Optimus

No one. This man is as confident as they come.

Jazz

Your violin. You practice so much that he thinks you love it more than him.

Ironhide

This bot is jealous of Wheelie. That miny bot flirts with you on the daily, and it catches you off guard sometimes so blushes appear.

Ratchet

Nobody. His wrench does the talking if someone gets too close.

Megatron

If he even gets jealous, he threatens that person/bot. Poor ST3v3 got thrown off a cliff.

Barricade

Your boss. He's dead certain that your boss has a thing for you.
