First show's the scene with the Maximals and Cogsworth bantering as described in A Maximal Crusader.

"What Happened with Cogsworth?"

We see the past Cosgrove smash the hard drive, followed by the current Cogsworth gathering particles from the Ashley Valley air space.

"I wasn't one to take any chances. He had it coming."

We see Cosgrove and Cogsworth tug and pull at each other while on the moving truck. We then see Cogsworth use the plasma grenade at Zipper before dragging him before Applejack, Cosgrove, Apple Bloom, and Scootaloo.

"You are so easy to forgive her too long after not thinking about me."

Apple Bloom huddled back against the desert rock as Cosgrove delivered the bad news.

"Galgameth is Cogsworth."

After being shutted out by Shock Drive, Cosgrove struggled to keep his thoughts in check, letting out a heinous growl.

"You're lucky that your parents are police!"

We then see the current situation as all the TV monitors in school gradually fizzled to show Sombra's face.

"Boss, we have an emergency situation!"

Tune in to this week's two parter:
