"The planet is speaking to you," Bumblebee repeats.

It's not the oddest thing that he has heard come from Optimus. The Primes have that weird sort of connection, don't they? Bee just isn't sure how the planet could be speaking without the Matrix. It's broken so isn't that connection also broken? These are things that he is never going to fully understand.

"So where do we go?"

Here he is: back to following Optimus Prime.
