This chapter is a set up chapter :3 the real fun happens after this.

Ratchet stalked through the base, his scanners searching for the human girl but he was getting some weird readings.

"Strange....." The medic murmmered then sighed, shaking his arm. "It says there is also an unitelligent Earth animal here as well.... seems that my systems are starting to corrode."

Ratchet walked past the hanger and through the corridors where the energon room was.

~~~

Sarah hunkered down behind some energon cubes, their soft blue light illuminating her face. Eyes burning with happiness.

"Oh my God, I can't believe I get to be Ratchets support buddy!" Sarah squealed but quickly covered her mouth when she heard heavy foot falls enter the room. Carefully she tried to wedge herself between two cubes, wiggling until she undoubtedly, got stuck.

"There you are." Ratchet muttered.

"H-hey." Sarah smiled, still in her awkward position. "Mind, helping me out?" She chuckled.

Ratchet sighed and went to move some cubes. As he moved one stack a cube began to fall, shattering on the ground.

Sarah, who was now free because Ratchet moved the stack keeping her captive, stared with wide eyes as the liquid flew towards her.

"No!" Ratchet yelled, servo slamming down before the human teen, but the damage was already done.

The medic flinched when a sudden high pitch shriek erupted. "Primus." He gasped.

The energon that splashed onto Sarahs arm, was burning her skin. Eating her tender flesh. (Sorry.)

Ratchets medical skills began to kick in, gently, but quickly, he picked Sarah up and ran to the med bay. The whole way there, the girl was curled into a ball, bitting her lip, eyes screwed shut from the pain.

Ratchet scanned her, checking to see if the energon was nearing her viens. He had to hurry.

Running into his med bay, he placed Sarah gently on the med table and quickly grabbed some tools that weren't in his sub space.

Once back, Ratchet hesitated. He knew nothing about the human body. He knew the basics, and what happened when energon touched a human; they would be burned.

Sarah whimpered but and Ratchet snapped back into reality. He silently cursed Wheeljack for not building the holoform file sooner. He could really use it now.

"Energon is eating it's self in to your arm and will reach your viens soon if we do not act." Ratchet said "I'm going to need you to hold still while I preform this. Can you do that?"

Sarah nodded her head and gave a weak smile.

Sarah felt the room spin. Ratchet had given her pain relief medicine after her little surgery. It worked in Sarahs eyes, because she felt down right giddy and loopy.

She remembered how gentle Ratchets fingers were. How carefully he held Sarahs arm. She didn't feel the burn nor the medical knife he was using.

However, she wasn't going to lie, it scared the crap out of her. But her fear was quickly washed away when he sat before the medbay table.

"Hi." Sarah smiled, trying to touch Ratchets large didget but she was severely uncordinated. Missing by a long shot.

Ratchet huffed. "Humans are such delicate creatures." It wasn't an insult, more of a compliment.

Sarah herd him mumble and her ears perked up, trying to hear his rich voice. Suddenly she saw him back up, optics wide.

"What's wrong?" She tilted her head.

"By the All Spark, what are those?"

Sarah gave him a questioning look before she realized just what he was looking at. Quickly she placed her hands over her head, hiding her ears.

"I-It's nothing." Sarah stuttered, bringing her knees to her chest. She cursed herself in her head. How could she allow her ears to slip out like that?

Ratchets finger gently removed Sarahs arm from her head. "It's alright. Let me see."

Sarah did as asked and watched with concerned eyes as Ratchet inspected her. Her cat ears twitched about in nervousness. She didn't want Ratchet to not like her, to think she's a f-

"Beautiful..." The medic whispered. His bright blue optics shining in wonder. Ratchets didget came forwards painfully slow, as though not to scare the teen. Sarah, seeing his hesitation, met his finger half way.

Ratchet breathed in amazement. His large didget brushed against the soft, delicate ears.

To his disbelief, the teen began to emit a noise. "What is it that you're doing?" He asked.

Sarah stopped, red faced all of the sudden. "I-I'm sorry." Her ears flattened against her head, eyes down casted.

Ratchet felt his spark skip. Gently he used one servo to cup her delicate frame, shielding her from the world around her. "What does it mean?" He asked.

Sarah raised her head a little. "I means I'm really happy."

Ratchet didn't understand anything about her. Or why she had animal parts on her. But what he did know, is that he needed to study her, protect her and....

Sarah felt Ratchets finger rub her head again. Melting instantly into his gentle touch as a purr left her lips.
