For a while Jazz was worried that all of Danny's focus was going towards his ghost hunting, that he was losing himself to this sense of justice, or maybe he felt responsible for all the ghosts?

Either way, she needed to check up on his mental health, but not in a way that would trigger him into emotional lockdown.

Luckily, she was able to find a perfect chance. As she was walking to lunch, she overheard Danny's friends say they were both going to be busy tonight with previous engagements. They said they'd try their best to sneak out, but he said it was fine.

She waited until he was alone and casually asked if she could join him on his patrol that night. She sweetened the offer by saying she could give him an alibi to their parents.

After dinner, Jazz and Danny went out for a study session at the library, or at least that's what they told their parents doing.

As they walked to the car and Jazz tried to think of a careful way to ask how her little brother was doing.

"Thanks for the cover tonight," Danny said as they reached the first stoplight.

"No problem, it's what big sisters are for. And if you want, we could do a bit of studying."

"Maybe if it's slow." Danny chuckled.

They made it to the library they both just sat there, maybe they were both waiting for the other to move first.

Jazz took the initiative and turned to face him. "You want to just walk around? I mean it could save energy that way, right?"

"I suppose." He shrugged and they both started their night stroll patrol.

They walked in silence until they got to the park and Danny just paused and stared up into the sky.

At first, she thought he was looking for a threat but then she noticed how relaxed he was just looking up into the sky.

"Nice night. You can even see the stars despite all the light pollution." She commented casually keeping an eye on his reaction.

A smile broke out across his face, "it's even better up there, above the cloud belt. Or out over the water."

Danny shifted into his ghost form subconsciously, but it seemed different than she was used to. His eyes seemed to shine a little brighter and something else she couldn't quite put her finger on.

He floated upwards until just the tip of his tail was at her shoulders, "Sometimes when it's a new moon I stay out just a little bit later so I can catch that short window of time when the streetlights go out and the sun hasn't quite risen yet, just to so I can see the Milky Way. It's amazing!"

"Do you do that often?"

"Well I can only do it once a month, and sometimes I forget what moon phase we're in until it's too late, but yeah I try." He looked back down to her with a smile.

That was when Jazz realized that it wasn't that his eyes were brighter, but his freckles were. Freckles that he had outgrown years ago.

That was it! He wasn't glowing with his normal ghostly energy, but with a youthful radiance and positivity. That being this focused on something he'd been obsessed with since he was a kid and-

Oh.

Obsessed.
