"Ratchet when are we going to tell the team the truth? Bulkhead's always been honest with me and telling me his secrets. My identity we have been lying to them about. My life is nothing but secrets and lies and I'm tired of it!" Bumblebee said.
Ratchet turned to her. "Bumblebee you know we can't do that now I promised your mom and dad I'd protect you and sometime soon we will tell the team. Just keep up the act okay." Ratchet said.
"Okay, but I don't like it." Bumblebee said.
"I know you don't." Ratchet said.
Bumblebee was tired of having her gender identity a secret. But Ratchet was just keeping her safe. He made disguise cover armor and put it on Bumblebee to make her look like a boy. Even made voice altering chip to make her sound like a boy and he told her to act like a boy. Which was becoming increasing difficult to act like one.
