Bumblebee was less on edge than Optimus when he realized from cade that Ratchet was killed in AOE. Considering that all three of them have come a long way in previous events; Was he pissed that there's no one else around to fix his voice or that Ratchet didn't try to finish fixing it in time??? Neither he nor Optimus even tried to recover his remains from ksi for a proper burial. Did they WANT ksi to finish melting Ratchets head after they left???
