JUST HAD A BULLSHIT IDEA OF WHY ONLY RAF CAN UNDERSTAND BEE.
The only ones who can understand him are Raf or a fellow Cybertronian. From what I remember... So! So! What if, Rafael when he was younger got an infection and had to get implants inside of his ear. And because he had an electronic filter, like a Cybertronian would have, he can understand Bee.
New headcanon, hell to the logistics. I'm not taking 'because he's the nerdy smart one' as an answer anymore.
