Ghosts are people who have unresolved problems in the living realm and choose to stay behind, however they cannot do anything to resolve those problems on their own.

part 3

Watching as she woke up was a silent figure in the dark. He watched every time she woke up, he could tell each time she became conscious but not fully awake. Her breathing patterns changed ever so slightly. He listened to the words that were said by her and those around her, but never was able to get his words across. He was overlooked by everyone, unnoticed, invisible, but he would not leave her side, there was nothing else he could do anymore anyways.

He spoke, but his words were never heard, after all what sort of ghost could interact with the living? He spoke anyways though, thinking aloud and wishing he were heard, or at least he did it to comfort himself since no one else could.

"So, now your memory is as bad as your eyesight shitty glasses, it was probably all those hits your head took. Though what the scouting legion will do with its mad scientist currently amnesiatic is beyond me, you're the one who thinks outside the box and always manages to liven up the place with your crazy experiments and lack of respect for order." He was sitting between the wall and her body, back against that wall. He had not left her side once, no need to now that he was dead, he figured.

It really was a sad thought, her not remembering him, but he was sure that she would bounce back in no time, she always did, no matter how much she took or who died, she would spring back up and be her usual self in no time. Then again, he knew that wasn't true, he had found her in those sleepless nights, those times of nightmares, he knew that she held everything that happened within her and didn't bounce back as seamlessly as she made it seem.

"You know, shitty glasses, you should recover soon, I won't let you just lay in here all day and night you know? Sleeping your days away is rather unhealthy, and you are filthier than usual." He sighed, knowing that he would not be heard but wishing anyways.

It was then Erwin came in.

"Ah good, commander, maybe you can get her up, after all she needs to do something besides sleep, last time you were here she woke up too."

To his surprise, Erwin did just that. "Wake up Hanji."

"Emmmuh? Whaaaa?" She sat up and looked at Erwin. Such messy hair Levi thought.

"You are being released from the hospital due to the fact that all of your injuries have healed, though you will be required to check in every so often due to your amnesia. You have been in here for 13 days."

"Have I? Hmm, well I suppose I must be taking up space that other soldiers need, it would have been logical to release me earlier really." This made Levi a bit angry for some reason.

"Hanji, you idiot, before today you wouldn't have been able to stand properly, you were healing, so naturally they wouldn't release you." Huffed Levi in frustration.

Unaware of Levi's scolding, Erwin spoke, "Hanji, you would have previously healing, pushing yourself too hard would have made it worse and made you stay here longer. I am here to escort you to your room as I assume you do not remember where it is."

Erwin offered Hanji a hand up, and while he was thinking that it should be Levi tending to Hanji, Levi was wishing that he could. She took Erwin's hand though and stood, allowing him to lead her through the castle to her room, with the unnoticed Levi trailing close behind.

The first thing Hanji noticed upon entering her room was a picture in a nice frame sitting on her bed stand. She walked over to it and picked it up.

"Who is this shorty in the picture next to me? He looked irritated and grumpy."

"Ah, that is his usual face, but he was probably a bit happier than usual, you just tend to annoy him sometimes, that is Captain Levi." Erwin said.

"I wasn't aware you still had that picture shitty glasses, it was taken ages ago, you were giving me bunny ears, joking about how I was as short as a rabbit. I made a remark about your obsession with titans and you just grinned taking it as a compliment, you always managed to annoy me by doing that but it was rather enjoyable really, our back and forth pokes at each other." Reminiscing again, he thought, hmm, being dead seems to make you do that a lot.

"Really? That is Captain Levi? Not what I was expecting from what you said about him, though I guess that just shows how bad my memory is if I don't even remember this picture getting tak-" She stumbled backwards, holding her head as if in pain. Both Levi and Erwin rushed to try and catch her, but while Levi was quick enough she fell right through him, and Erwin was too slow so she fell to the floor.

"Aaah, ah, my head, it huuurts!" She wouldn't stop holding it, and so Erwin bent down to make sure that she was okay while Levi wished he could do something, anything at all.

"What is it shitty glasses? You alright?"

"Are you okay Hanji?"

Levi and Erwin spoke at the same time, though Hanji only looked up at Erwin. "I, I think I will be fine, but, I remember what was happening when that picture was taken now. It, it must have triggered my memories, by looking at it. It was a nice memory, that much I can tell, everyone around was smiling, even Levi, under that annoyed face of his."

"That's right Hanji, I was smiling, though I suppose you were the only one that could actually tell, considering how well you can just read me, and find my emotions written all over my face, to you that mask of mine never existed." He sighed, frustrated at death in general. He had always said that he would accept his death when it came, but now he didn't want to, only when he actually had something to live for did he die. How ironic he thought.

"I wouldn't be able to tell, you were always the best at reading his emotions, he kept a mask on most times. And I wasn't there either so I wouldn't know the scene." Erwin said. "Anyways, if your head hurts too much you should lay down and sleep, I figure that even though your body is recovered your mind still has a long ways to go."

"Alright, good idea." She climbed into her bed and laid down, from what Levi could tell she was out like a light. The walk to her room had probably tired her out a lot considering she was still recuperating, and regaining memories seemed to take its toll on her too. He settled down into a chair in that room, and watched over her like a faithful guard dog, watching the rise and fall of her chest, consoling himself that even if he couldn't interact with her at least she was still alive, and hopefully had much more life to live.

Poltergeists are much different from ghosts. Poltergeists are the ones that can move objects, though it requires a lot of willpower and mental strength, determination and a goal.
