Eren now finds himself standing in a bedroom. He took in his surroundings as it held some familiarity to him.
As he looks over to the bed he notices a body laying underneath the sheets. He could hear soft snores from the body. Eren approaches the bed peering down to find it is himself sleeping.
A muffled sound of voices erupts from the outside of the bedroom door. Eren walks over pressing his ear against the door to listen.
"I'll check on him Armin." The voice says, and Eren immediately knew it belonged to Y/n.
"No problem. He's been out for most of the day. I'll keep Mikasa occupied since she seemed worried from the experiment earlier." Armin replies.
"I'm sure she will be fine, but she shouldn't stress out too much since she is still recovering from her injury during the squall with Reiner and Bertholdt." Says Y/n.
The basis of the conversation indicated that Eren was in the cottage within Wall Rose. It was during the time the Survey Corps had been temporarily disbanded, before he was kidnapped with Historia to the Reiss Chapel.
Presently, Eren was in the memory from one of Hange's experiments having failed in transforming into his full titan. He remembers now that he spent most of the day regaining his strength.

He backs away from the door as it opened as the young Y/n quietly enter the room.
Y/n walks over to the bed pulling a chair with her to where Eren was currently sleeping. She could hear is soft snores as he laid on his back. Y/n reaches her hand out to push away some of his brown locks from his forehead. She then starts running her fingers lightly through his hair. His face starts to relax with the gesture causing Y/n's eyes to soften and a smile gracing her face.
"You're probably tired from everything." She whispers out loud. "I wonder if he has a fever." She questions as the hand that was playing with his hair moves to rest on Eren's forehead. His head felt warm to the touch so Y/n decided to leave the room.
Eren had made himself comfortable on top the desk in the bedroom as he watched Y/n check on him. This was a different memory from normal as his younger self was unconscious. He pondered whether this was his memory, or was it Y/n's.
The door creaked open again redirecting his gaze back towards the girl.
Y/n entered the room once more carrying a small bowl with water and a cloth hanging from the side. She sets the bowl down on the corner of the desk that was closest to the bed, and situates herself back on the chair once more. She dips the cloth in the cool water, squeezing out the excess liquid, and then placing the cloth on his head.
The cool sensation meeting Eren's forehead caused him to stir in his sleep, until he relaxed once more adjusting to the touch. Y/n repeated the same motions a couple more times gathering water on the cloth and placing it on his forehead.
Eventually Eren's eye lids begin to flutter open. "Mikasa I'm fine. I'm not your kid..." He mutters out. Y/n lets out a soft chuckle. "It's Y/n, silly." She says to him.
His teal eyes shift towards Y/n meeting her e/c ones. His body relaxed as he saw it was Y/n. "Oh sorry." He awkwardly says as he slowly sits up from the bed.
Eren looks at Y/n questioningly. "What happened? I don't remember anything." Y/n lets out a sigh as she explains to him. "You didn't fully materialize. After you got 75% of your titan, you collapsed. Hange was freaking out, and tried pulling you out from the titan. Mikasa was starting to get stressed from you not waking up. Anyway, Jean and Armin carried you back here." She finishes her explanation looking back at Eren.
