Hospital wing

Dazais pov

Chuuya, Dazai and Harry spent the next few hours- or days in Dazais case, lying on the uncomfortable metal beds in the hospital wing. Ron and Hermione were the first to visit the trio, bringing food and chocolates from that days feast. Dazai smiled as he watched Chuuya and Harry talk with them, and he smiled even more when he noticed Chuuya shoot glances at him from over Hermione shoulder. 

He rested his face in is palm, watching the four with his head peeking from the curtain that was drawn around his bed for privacy as Mrs Pomefrey bustled next to him, rummaging through her supplies with her brows creased and lips pressed together in concentration.

After a few minutes, she finally sighed, giving up on what she was searching for to turn to Dazai. Dazai noticed her slightly smirk as she followed his line of sight, but she didn't say anything. "Im not sure how, Dazai, but you've managed to empty both of my bottles of serum without the magic having effect on you. It's surely a first for me" she raised a brow.

"Does this mean Im special?" He said obnoxiously batting his eyelashes.She ignored his comment and set her drink on the table. The straw clinked against the glass as she did so. She heaved a sigh and Dazai started to wonder if she was drinking water of vodka, and if it was the latter, he was a strong believer that sharing is caring.

"I'm going to have to run some tests with the doctors from Saint Mungos'" She explained, and Dazai chewed the inside of his mouth "The thing is" She explained "I believe it has something to do with either certain muggle pills that you've taken in the past, or something else thats mixed in with your blood."

Dazai froze. He had to tell Chuuya. No.. he wanted to tell Chuuya, he should tell Mori. A bitter taste found itself in his mouth as he weighed the consequences. Why not tell both? He felt himself cringe as he imagined him trying to write a letter to his boss. He's such a dick. And not a good one either.

He pushed his thoughts aside and looked up and the nurse and smiled "Works for me" He said finally. And she handed him a slip of paper detailing when he would get his blood sampled.

Only a few minutes later Draco Pansy and Blaise were let in his hospital room, as they crowded around him, Dazai put his hands behind his head and started smugly rattling on about his success of capturing the egg to Dracos annoyance and Pansy's distaste.

-Later that night-

Though Dazai was told to stay in the infirmary for one more night, Chuuya and him snuck out anyways.

As they wandered the corridors Dazai explained the bloody situation- as he liked to put it (Pun intended). With Chuuya half heartedly nodding, too tired to grasp any information.

They came to a halt in front a large mirror but inside it was nothing. Chuuya stopped too. "What are you looking- what- what the hell?" He said in a slightly raspy voice.

Where Dazai saw nothing in the mirror, Chuuya seemed completely transfixed by, his brows furrowed and a tint of rose adorned his cheeks. Dazai giggled "Waddya see?" He asked, nudging the ginger in the side.

Chuuya shook his head slightly and pushed him off "My reflection, leave me alone dipshit" he said finally Dazai snickered. "Are you sure thats all?" 

HC for my HP x BSD Headcannon: In the mirror, Chuuya saw himself surrounded by people, but where there should be, well, a person, instead there was just the outline of a blurred figure except for one person who had a firm outline but still no filling (Think of it like a strange blind spot) } That person is Dazai and the reason he is slightly blurred is because his ability makes it so that when using magical objects he is visible but much less compared to others.

[But obviously the reason this isn't mentioned in the text is because I want it to be the readers choice of what Chuuya sees; this is just the closest thing to my particular canon for my fanon]
