Will trashed around on his bed. He just couldn't sleep. Since his first interaction with Nico di Angelo during the war something had snapped out of him. A worry that wouldn't leave him alone, a mystery that needed to be solved.

Why is Nico like this? Is there some way that I can help him?

Those questions, wandering inside his mind every single night and Will had enough of it.

First hour in the morning he woke up Austin and told him to lead the Cabin for a day together with Kayla, he would be busy and couldn't do it himself. He proceded to get out of his Cabin, jogging towards the Big House. He entered without even knocking slightly surprising a sleepy Chiron.

-I need to talk with you, it's urgent.-

-Very well, Will. Take a seat at the ping pong table, I'll join you in a bit.-

The son of Apollo kept looking around the room, tapping the table anxiously with his fingers. Five minutes later the door opened to reveal the delicious smell of sunny side eggs and bacon. His stomach growled, Will didn't even registered being hungry until the food was in front of him.

-I noticed you were acting stressed this last weeks, I thought it was the war but, I have a feeling that it might be something else, am I correct?-

-I... I don't even know were to begin with—Solace stayed silent for a minute— I guess I would have to tell you our somehow illegal activities and my own conclusions since I treated him.-

Chiron looked up from his meal only to nod, patiently waiting to hear the end of the story.

-You know that I've admired him since I met him and to see his development through the years is a shock to me, an injustice that I wish to correct. I know I can't do it without his cooperation. These last two weeks we have been spying on him, and as in we I refer to his friends or want-to-be-friends. I have notice that he tries to be okay but I know he is hiding something and my confirmation happened yesterday when he was talking to Drew. Also during his recovery after the war he had nightmares, he didn't scream but if you saw his expression, specially right after he woke up from them you'd notice his eyes full of panic and fear. I don't know what happened to him but to know how affected he is it makes me regret what I told him.-

At that point Solace had to take a break, he said everything so fast that he doubted Chiron even understood it.

-As I understand—Chiron interrupted his thoughts with his always calm voice— you suspect Nico has something severe, as in a sickness. Explain that to me and also I want to know what kind of illegal activities were you doing.-

-We were—he cleared his throat— we were spying on him using Hecate's magic. And I want your permission to sky him all day long, before he wakes up and after he goes to sleep. I need to check up his symptoms and signs.-

-Tell me, Will, what are you suspicious of?-

-Of Post-Traumatic Stress Disorder.-

The centaur leant in further on his wheelchair rubbing his chin, considering what Will just told him. Without looking up he said.

-You understand that you must keep this as a secret?—Will nodded— Very well, you must ask miss Ellen for assistance but, both of you must swear under the River Styx that you will not talk about this with anyone without Nico knowing first, am I clear?-

-Yes, sir.-

Will stood up and walked to the door.

-One last thing,—Will turned around— if you regret whatever you told him, you should apologize. Mr. di Angelo is not someone who appreciates people who hide things from him, so be careful on how are you going to tell him about this later.-

-Okay, Will, I get it. But why would you think this is so serious? Everyone has got some sign or symptom of PTSD.-

-Yes Lou, but not like him. I think that that it's the reason why he won't get better even though he is receiving medical attention.-

They were hidden in the Big House basement. Will had lost no time on waking up Lou and kidnapping her away from her siblings. She started some chants in Greek, sacrificing food for her mother and playing with the mist that gathered around her. Suddenly they were looking inside the Hades Cabin were a mop of black hair was poking out of under the blankets. They zoomed in only to see a deep frown and tears coming out of the boy's eyes.

They continued around the day were they encountered different situations. The first one was right after breakfast:

-Hey, di Angelo! Guess what Travis said?-

-I don't know Connor, what did he said?-

-I said, —Travis appeared behind Nico— that if you continue to eat so little that you weren't going to grow up and would stay this short, so short that I bet you could fit inside a jar!-

Both of the Stoll brother were cracking up until the shadows starting moving under them.

-Do not —di Angelo said his and unusually cold and calm voice— ever mention something like that ever again.-

The second thing they observed was later that day after sparring class.

-I don't know, man. Marine biology seems fine by me.- Percy commented.

-Really? I guess Annabeth is affecting you a lot. For my part I still haven't decided but maybe study laws or something like that. Maybe I can be a negotiator between the camps and the gods. What about you, Nico? You'be been extremely quiet.-

-I don't know—he started fidgeting with his skull ring—I don't think that it matters—he shrugged his shoulders in sign of indifference the he leaves.

Nico was walking back to his cabin, examining his surroundings in search of a threat. He knew he's supposed to feel safe here but, he just doesn't, nor anywhere for that matter.

When he opened the door to Cabin 13, he was greeted by and Iris message of Hazel. They talked a lot, well, rather Hazel talked a lot and he just watched her, he really wanted to pay attention to her but, he just couldn't.

-Are you even listening to me, Nico?-

The son of Hades jumped in surprise when his sister called for his attention.

-I...er... yes, sis.-

-No, you were not! Nico, listen, I worry about you but, this isn't the first time that you drift away, and not only when someone is talking. I've talked to Piper, she told me you even get distracted while eating and during many other activities and that could be dangerous. Please, search for help, and don't try to act like you're fine, because you're not!-

Nico looked away -I guess you're right, I'll search for help, really, I promise.-

After lunch, di Angelo was making his way through camp, he was almost at the border of the forest when he suddenly felt dizzy and almost fell to the ground.

-Got ya, cupcake.-

-Hello, Coach, how's everything?-

-Well, being a parent isn't easy, you know? But I like it anyways! You don't look good, kiddo. Are you alright?-

-Yes, I'm fine.-

-Don't lie, Nico.-

-I said I'm fine!- the demigod snapped and quickly felt guilty about it. -I'm sorry, I didn't mean to snap like that.-

-Don't worry, remember that I know what you've through but listen, acting like this for so long ain't normal, either you do it on purpose or not, it is affecting your health and I know it, I can feel it, you know, spirit of nature and all.-

It was almost curfew time when Lou and Will entered Chiron's room.

-Will, Lou, I hope you found something relevant.-

-Yes sir.—affirmed the healer— I checked his reactions to situations during the day and that only proves my suspicions. PTSD's symptoms divide into four categories, the first one is revival of the events in which one of the signs is that people get strong reactions when something reminds them of a traumatic event, the second one is evasion in which Nico shows feeling of indifference and an unclear future. Then, the third one is hyperarousal where he also shows some signs like hypervigilance, being unable to concentrate, being jumpy and feeling grumpy. Also he shows signs of anxiety, stress and tension like dizziness. At least these are the ones that happened today.-

-I have a feeling that there is a but, am I right?- asked Lou

-Indeed,— Solace affirmed going again into his full doctor mode— I have observed other times, that he feels guilty about something, I don't know of what but, sometimes his facade slips and you can see that he isn't alright at all, also during his stay on the Infirmary I noticed that he has difficulties to fall asleep when he is not exhausted to death. Again, during that time, we connected him to a heartbeat meter and his heart frequency is always high, and he complained that he felt really extreme palpitations, so this lead to some headache.-

-Very well, keep observing his progress, in the meantime try to find a way to tell him all of this.-

-Of course, Chiron.-

-Will— Lou Ellen said while they were walking to their cabins— do you think he will accept your help?-

Will stopped his tracks -I hope he does, if he promised something to Hazel it means that he'll do it. —the son of Apollo sighed— I just hope he will accept my help soon, it really breaks my heart to see him like this.
