Waking up with someone else's memories isn't a pleasant experience.
Knowing your past self's bots are going to arrive today, in four hours at the coordinates Jack remembers, isn't that pleasant either.
So of course, Jack arrives at the coordinates via the ground bridge (and convincing the others he doesn't need company), and has five seconds left to spare.
A bright light appeared and Jack covered his eyes with an arm, blinded as he took a few steps back. As the light faded, Jack lowered his arm and blinked a few times to regain his sight.
Everything was still blurry as he heard a familiar baritone voice ask in disbelief, "Ratchet?"
"Optimus?" Was the shocked reply from a voice that could only belong to Ratchet. "I… How are you here? Where are we? Is… IS THAT A DINOBOT?"
Now able to see properly, Jack couldn't help but laugh at Ratchet's expression. Feeling questioning and suspicious optics on him, he calmed down and said, "You bots are here because of a malfunction with a ground bridge, which you guys were next to.
"Welcome to Jasper, Nevada by the way. And I didn't realise there were dinobots; pretty sure Sam didn't have that in his plan," Jack mused.
"You know Samuel James Witwicky? What was his plan?" The flamed Optimus asked, seeming to inch closer to the Cybertronian T-Rex.
"Well, I am his reincarnation, and I just go this memories this morning, so I'll probably forget a few details of his plan. Basically, after the whole Sentinel thing and Ironhide dying, Sam knew that it was only a matter of time before the rest of you died. So, he studied the theory on other dimensions, and after three years he had his plan ready to set into action.
"That ground bridge you created, Ratchet? Well, that is what Sam planned on using to get you lot away from the eventual destruction of Earth, but it didn't go to plan." Jack paused, taking a deep breath as he looked at the shocked expressions of the autobots. "Sam was captured by Barricade and tortured for autobot secrets. Never said anything, of course. Eventually, Sam died a few days later from starvation, dehydration and physical and mental trauma.
"Thus, the plan to save you guys died with Sam. Thank God that you put in the right coordinates to send you somewhere else. Although, you could have been sent to a dimension that has no cons; can't trust travelling dimensions, they can send you anywhere."
"Sam died?" Ratchet murmured, upset. "I…"
"It's not your fault Ratchet," Jack said firmly, knowing exactly what the medic was going to say. He looked at Optimus. "It's not your fault either, Optimus. It's Barricade's fault. Let's get you lot somewhere safe, hey? Dinobots, stay here; you'll be able to help when Optimus, Ratchet and I get back. Ratchet and Optimus, you'll be with me to go to the scrap yard to get some metal to build a base.
