I was never an expert in the hows and whys of the Matrix. Although I am pretty sure that I never saw it used for spark ignition. All I know for sure is that when Optimus showed up after the reset of the planet, he had two halves of the matrix's shell. He gave one to Bee and one to Rod.

['Jack is more interested in the piles of scrap - he starts sifting through the piles looking for bits and pieces with potential. He's still listening, of course, nodding and making small noises where appropriate, but every so often he digs out something and tosses it towards the bigger mech.]

Hmm, yeah that sounds a bit different than what happened to us. But the end result was almost the same - a rebooted planet. Although a restarted Cybertron under Shockwave's command? [He makes a face, or well, as much of a face as he can]
I'll pass on that.

It does make me wonder though - if there really is some space-time disturbance affecting Cybertron. All of them, across realities. Granted all I know about is yours and mine but still. Makes me wonder.
