"You don't need to thank me," Bee replies with a simple shrug. "There's a part of me that's still skeptical, but I'm not going to give you a chance when you've earned it. You gave me reason to and I'd like to think that you wouldn't pick up the Autobot's badge - my badge - and not try."

It's a little bit of trust and another bit of expectation. Megatron is wearing Bumblebee's badge and many people probably know it. If Megatron is going to continue to wear it, then he should try to live up to what it means - if not for himself, then at least for Bee's sake.

Bumblebee isn't above using that barb. He's not a complete soft spark.
