Ratchet gets to know the Dragonformer who helped him and incites her to stay with team Prime. A little time passes before (Y/D) realizes she's fallen for Ratchet, and it turns out Ratchet has fallen for her.

Ratchet wakes up, uncertain how he got into a way cave and on a comfortable bed. Then he remembers what happened; damn Decepticons, but how did his injury heal already? He's able to transform and walk around the cave. Ratchet finds it strange the cave looks lived in. There's no way humans got him here either.

Discovering humans did get him here would be impressive, but seeing another cybertronian is surprising, and they are also a dragonformer who has a good amount of Energon.
"Look who got up," she teases as she hands him an Energon cube,
"you're cute," she teases before walking away.
Ratchet is shocked for a bit before blushing a little and drinks the Energon, which isn't bad at all, but the richest Energon he has tasted since Cybertron fell. It quickly replenished his systems.

Ratchet finds the femme standing at the entrance of the cave and stands next to her.
"I appreciate what you have done, but I have questions that need answers."
The femme nods.
"What faction are you?" Ratchet asks.
"Neither."
"Where did you get the medkit?"

"A dying Decepticon; I was a medic, but seeing all the injured cybertronians from the est became too much."
"Why didn't you join the Autobots? We could have used someone with your skill."
"I didn't want to get involved at all, the fact the war in its core is just two people fighting over their believes. Prime is a good mech, but Megatron is right as well. Being neutral, I see where both are coming from. Megatron is a long-term type bot while Optimus is in the here and now. He wants freedom but afterward, what is left? The same rules that made Megatron who he was is still going to be there; nothing is going to change. Megatron wants to change, but he isn't doing it the right way neither of them are."
Ratchet sighed and told her he felt the same, but he chooses to help.
"If there is someone in need, it's your duty as a Cybertronian to help. Even the humans on this planet say it's the right thing to do."
(Y/D) mods but doesn't say anything else. Silence fills the air until Ratchet finally speaks again.
"Would you like to head back with me to the Autobots?"
(Y/D) thinks about it, worried she'll be roped into joining the Autobots, but their base is better than a cave.
"Yeah, sure."

The two put everything from the cave into their subspace and head back to the Autobot base.
"Ratchet, are you ok? I have been trying to contact you," Optimus says before seeing the other cybertronian, "who is this?"
"This is (Y/D); she is a neutral."
"Understood, any Cybertronian is welcome. It's late. If you don't mind, Ratchet (Y/D) will have to share a room with you."

Ratchet shows (Y/N) his room before going to the medbay to check his systems for damage.

He walks into his room, seeing (Y/D) on his berth, with enough room for him, but they'd be close to each other. He knew the femme wouldn't let him sleep on the floor, and he can't have her sleep on the floor. He blushes at the idea they'll be close to each other as they sleep.

The others enjoy teasing Ratchet the next morning about how he left to see his secret girlfriend until (Y/D) rages at them, which results in Optimus lecturing them how (Y/D) is a fellow Cybertronian who's neutral in the war. As of now, (Y/D) feels uncertain if she should stay here or not.

Three months pass; (Y/D) thought she would have left after a few days, especially since the other mechs, aside from Optimus, kept claiming she and Ratchet are together. The truth is she is falling for Ratchet. Between the teasing and only knowing Ratchet for three months, (Y/D) is uncertain if she can tell Ratchet how she feels, especially when Ratchet argues they're not together.
This could mean he's not interested in dating me. (Y/D) thinks as she sits on the berth.

Even when Ratchet suggests they go for a walk, (Y/D) doesn't think Ratchet is about to tell her he loves her. She stops in the middle of their walk, which troubles Ratchet.
"What's wrong?" He asks
"Nothing."
"I've been around long enough to know when someone is lying and when something is troubling them; what is wrong?"
Ratchet makes sure (Y/D) can't leave. She knows the longer she makes Ratchet wait, the more pissed off he'll be. Ratchet doesn't like that (Y/D) is trembling as he takes her servo.
"I-I love you," she nervously confesses.
Ratchet says nothing, which worries (Y/D). She tries to run, but he stops her.
"I love you, too."
He kisses her, which quickly gets heated until they fall to the ground and take each other's interface panel off. Ratchet has been wanting to frag the femme he's fallen for. He doesn't wait until she's ready; he goes right in and feels how tight she is. (Y/D) moves her hips, allowing more room. Be feels her getting wet and able to begin moving in her. (Y/D) is amazed by how long the old mech can go. Not caring he cumed inside her, not caring she might end up sparked. Ratchet is shaking from what he did and struggles to pull out. (Y/D) had him lay on her to relax and nuzzles his helm resulting in a purr from Ratchet. He finally relaxes and pulls out, but the two aren't ready to go back to the base; they cuddle and kiss.
