Who Guards the Guardians? (TFP/Bayverse crossover)

Survivors

Ratchet quickly springs into action. He doesn't hesitate to clear off a table by swiping his arm across it. "Lay her there!" He moves towards large computers, removing a sticker from Fowler that read 'Hope these suffice. Don't break them. It's all you're getting.' He throws the sticker away and begins powering them up. Wheeljack, having laid Rachel on the table, lifts up Lennox who barely waits for him to be level with the large table before jumping off and rushing to the girl.

"Rachel!" He shouts, sliding to a stop by her. He lifts her head onto his lap and feels for a pulse. His eyes widen, but not in fear.

In confusion.

"Ratchet! She still has a pulse! It's... It's erratic! What's happening?" The medic gazes at him, and grunts, then continues with his work. He types a few more things, then connects a tube to a cylinder. "I need energon, now!" He turns around. Gazing at the crew. Bulkhead sputters. "E-Energon?! Isn't that deadly to humans?!" Arcee starts to agree, but Ratchet growls. "I don't have time for your questions! She is dying, and I need energon. Refined. Energon!" Before anyone can ask again, Optimus speaks up.

"I will offer my own."

The whole team turns toward him, shocked. "Optimus, we can't let you do that. If you run out of energon..." Arcee lets the sentence hang, but the leader shakes his head. "I will not let one of our own perish when we can help...." He walks over to Ratchet, extending an arm. However, another servo clasps over it and pulls him back. "No. Arcee is right." Wheeljack's solemn face rises, and he locks optics with Optimus. "Can't have the big boss dying on us." He then extends his arm to Ratchet. "Take mine."

Optimus gazes at the Wrecker, but Ratchet quickly inserts a needle into an exposed energon line. Wheeljack's faceplace scrunch up, but he doesn't move or make a noise. Despite his lack of noise, the ruckus from earlier awoke Smokescreen, who was now sitting on the edge of his berth gazing at the scene before him. Worry was evident in his optics as they fall on Rachel's body. While the cylinder fills, Ratchet turns to Major Lennox. "Will! Take this IV drip, on her right arm, there is a button. Press it and it will implant a needle directly into her bloodstream. All you need to do is insert the drip needle into the small hole that will appear." 

The Major nods and searches on her arm. Finding the button hidden under the jacket sleeve, he presses it and a small tube appears as the clothing dissipates and turns back into the armor. Rachel makes no noise as the needle jabs into her arm. As Lennox prepares to insert the needle, Ratchet removes the needle and tells Wheeljack to hold the small hole on his arm for now. He then rushes over and connects a tube to the bottom of the energon filled cylinder to the top of the iv bag. He then allows it to fill completely, making sure no air is in it. Once filled, he shouts, "Now, Lennox!"

William carefully but swiftly inserts the needle into the suit, watching the young woman in anticipation. For a while, nothing happens, and Ratchet turns to the computers. He inputs a few things, and Rachel's vitals suddenly appear on screen. "Sparkrate is still erratic. The energon hasn't reached it yet." The whole team turns towards him, but he doesn't speak anymore. Instead, he pulls up her x-ray, revealing a stream of bright blue slowly going up her arm towards the large, pulsing light in her chest.

Wheeljack gazes at it before his optics widen, Smokescreen mimicking the action. He turns towards Ratchet, who only shakes his head before turning back to the young woman. As the blue line of energon slowly makes its way towards her spark, Optimus turns to Ratchet. "Ratchet, can we do nothing else?" The medic shakes his head. "All we can do now is wait..... And... I can tell you what I know, which isn't much."

Bulkhead, Bumblebee, Arcee, and Optimus turn to face him. Ratchet, grabbing some large gauze from a storage in his hip. He motions for Wheeljack to sit down, and the Wrecker obliges. As he wraps up the needle prick from the transfusion, he speaks. "All I know is that, around five years ago, she had some sort of operation on her heart, and whatever they did.... they replaced her heart with a cybertronian spark." He finishes with Wheeljack and turns back to the computers. He zooms in on her spine, showing the tendrils that were forming around it.
