It's probably gonna be the second last chapter. I decided to make this all a four-chapter story. Ok? Ok. Also, be sure to check my work on Wattpad - it's called 'Exchange Students - A 'Percy Jackson' and 'Harry Potter' Crossover"

P. S. - I was listening to all the songs mentioned in here whilst I wrote this. Those are probably my favourite songs of all time.

Chapter Three: In Which the Three are Confused

Jason and Leo rushed to the infirmary straight after Piper. They saw her and Annabeth carrying a limp, unconscious body to the infirmary. After hearing Will yell through the building they realized whose that body was.

- Di Angelo! I swear, if this is not going to kill you, I definately will! - his voice was just radiating 'I'm angry. Do NOT bother me!'

The two new campers looked at Will. It only confirmed their worries about Hades-Apollo kids' relationship. Altough they didn't know why, the campers seemed like they could drown each other in a spoon of water or burn with a small match just to get rid of each other. The way the demigods from Cabin Seven told their relationship was 'interesting', and then walked away without even explaining, and the way their conseulor yelled at Nico di Angelo, knowing well that he didn't hear.

- He probably doesn't want to waste his time. - whispered the son of Hephaestus.

- Yeah. Maybe we should check on them sometimes? Because this Hades kid looks like he's going to stay unconscious for at least a week. - agreed Jason.

Piper approached the boys, with the same worried expression on her face.

- I wonder how their other meetings in the infirmary looked like... (Probably... Interesting [If you know what I mean ;)]) - said the Cherokee quietly, watching as the son of Apollo muttered 'Paradise City', touching the boy's forehead with his palm. But it wasn't enough to at least make all the wounds disappear.

The trio could now see that his pale olive chest was covered in bleeding claw marks, and he was shaking terribly. The healer switched to another song.

- Here comes the sun... - whisper-sang Will, in his usually great singing voice.

It took not only the famous 'The Beatles' song, but also 'Burning Love', 'Satisfaction' and 'Nothing But a Good Time' to make the skinny, short son of Hades conscious again. The new demigods still didn't quite get why the healing hymns were replaced by famous rock songs, but they didn't also complain. Nico di Angelo coughed quietly, and his eyes fluttered open.

- W-will? Whe- the son of Hades couldn't finish his sentence because of the sudden cough attack. Due to the freshly healed wounds on his chest it must've been a really unpleasant experience.

- Don't speak. Or move. For your own good, better go to sleep. You're in the infirmary. Because you shadow travelled, di Angelo. After I told you not to. You better have a proper excuse, or else... - spat Will harshly.

Nico just nodded weakly and put his head on the pillow. Will told them all to go out, because the patient had to rest.

- Oh gods... I wonder what would the infirmary look like after the two spend too much time together... - whispered Jason.

- Hey, remind me of something, can you? Why are we so interested in it all? We're not even sure if we're interpreting it all right! - said Piper. She really didn't see much sense in it all now. Leo just looked in her eyes and said:

- One: Because we can. And two: Yes, we are!

The trio came back to the infirmary after Nico's twenty-four hours sleep. They wanted to visit the guy, even if they didn't really know him. It was the time to get to know him then. They all knocked at once. The only response was a silent 'Come in' interrupted by some coughs. Piper, Leo and Jason saw the small silhouetto wrapped in the blankeds, with his eyes shut tightly. On the small table beside his bed there was a mug of hot tea with nectar, and some ambrosia.

- Hey, you are Nico, right? - asked Piper awkwardly.

The son of Hades slightly lifted his head and looked at them, then nodded. The girl continued.

- I'm Piper. Annabeth and I found you near the forest. And these guys are Jason and Leo. - Leo waved with his usual mischevious smirk on.

The awkward conversation, fortunately, didn't have to go on, because Will Solace himself, wearing not scrubs, but a navy hoodie, grey sweatpants and navy Chucks, stormed into the room.

- Good, I see you're awake, di Angelo. Now, answer my question from yesterday: why did you shadow travel? You know that you hadn't had enough energy for another jump!

The trio saw the look in Nico's eyes... Was that sadness?

- I-I'm so sorry, Will. I wouldn't have to jump if those stupid hellhounds didn't interrupt. - murmured the son of Hades quietly. Will kneeled next to Nico's bed, this time with a softer expression.

- After you said why, I should be the one that is sorry. I didn't have to yell at you. But you know I cannot get angry at you for more than two days.

Slowly, Nico sat up, his black hair in a giant mess. He had a Camp Half-Blood tracksuit-thing on: a way too big orange hoodie, black sweatpants with a white CHB written on the right leg. The final thing were the fuzzy white socks. Nico didn't really look like the gloomy, always mysterious son of Hades the new campers expected him to be. He wrapped his arms around Will, pulling him up. The son of Apollo wrapped his arms around Nico, standing up and lifting the smaller boy.

- C'mere, Neeks. - Will, smiling, placed him on his back, giving Nico a piggy-back ride.

- Did you know that you smell like marshmallows and Mountain Dew? - muttered Nico into Will's neck. That made the healer chuckle.

- That's OK. I hope you like marshmallows and Mountain Dew. - Nico nodded, nuzzling into the taller boy's neck.

- I really like marshmallows and Mountain Dew.

- Good. Now come on. You won't be staying all day in bed, but you can as well ride me as long as you want. - Nico laughed and leaned over Will's shoulder, placing a kiss on his cheek.

They didn't notice that the three new demigods were still in the same room. Nico blushed crimson red, but Will just smirked and said:

- I told you that our relationship is interesting.

And with those words, they left the confused trio alone in the infirmary, all thinking:

- What the actual heck?!
