AN: We're almost at the end; there's one bonus chapter (prom) left after this!

Hazel smiled and leaned against Frank's shoulder as she watched her soulmate play Mythomagic with her brother.

'Dang it, I forgot about your Katobleps!'

Nico smirked.

'You know I have an Africanus Expansion pack, Zhang. That's the second time you've made that mistake.'

Frank rolled his eyes good-naturedly.

'You might be beating me in the Mythomagic tally, but if we gave chess a go...'

(No-one, save Annabeth, could beat Frank in chess. And even Annabeth had only a 40-50% win rate against him.)

'Not my game, Frank.' Nico smiled. 'But how about a rematch?'

'Play with each other's decks?'

Nico nodded.

'Why not? I could do with a challenge.'

Frank pouted.

Hazel slapped her brother lightly on the arm.

'Nico! Play nice!'

Nico frowned, but his eyes were light and teasing.

'How can I play nice when you're so obviously biased? You want him to win!'

Hazel shook her head, smiling.

'Nico, you both know that I'm not taking sides.'

Nico raised an eyebrow. Hazel was sitting on Frank's side of the game area.

However, before he could tease her about it, a rather hyperactive shirtless blur in red shorts flew past.

Leo ran through Piper's living room (thank the gods neither her father nor her father's assistant were home), carrying a tricked-out water gun.

'Save me! Anybody! Somebody!'

Frank, Hazel and Nico just stared.

His pleas made more sense when Calypso ran past a few seconds later, her white dress soaking wet and semi-transparent. They all turned away, rather flushed.

'Leo Valdez! You are so dead!'

Leo paused for just a second.

'Aww, I love you too, Sunshine!'

He glanced at his fuming girlfriend, before setting off again, running towards the kitchen. Calypso paused, shook her fists, and took off again towards the kitchen.

'You are full of it, Leo Valdez!'

Nico, Hazel and Frank just shared a glance.

'Maybe we should have our rematch outside.'

Nico nodded.

'Good idea, Frank.'

Hazel, too, nodded.

'We definitely don't want to walk in on them...err...making up again.'

She fanned her face, flustered from the memory.

Frank, Hazel and Nico set up the Mythomagic game outside.

Beside them, Reyna and Jason were having a conversation on the pool edge, discussing some plans for student government, even though it was summer.

Piper was swimming in the swimming pool. She swum up to Jason and Reyna, and splashed her soulmate with water.

Jason yelped.

She smiled at him.

'Jason...'

The blonde boy sighed, pulled off his shirt, and got into the pool.

Reyna shook her head.

'He's so whipped.'

Percy seemed to draw inspiration from Piper, because he seized a water gun that was lying on the floor and shot Annabeth (who was reading the newspaper) with it.

'Seaweed Brain!'

He flashed her a winning smile.

'Yes, Wise Girl?'

Moments later, Percy found himself in the swimming pool, fully clothed, spluttering.

'You deserved that.'

Annabeth stood on the pool edge, dripping wet, arms crossed, looking rather satisfied with herself for pushing him into the pool.

In response, Percy climbed out and dragged her in too.

'Pool party! Come on, Frank, Hazel, Nico, Reyna! And Leo and Calypso if you can hear me! The water's great!'

Annabeth simply rolled her eyes fondly at the swimmer. He would never change.

Hazel and Frank shared a glance. Hazel had her swimming suit on underneath her clothes, and Frank was wearing board shorts with his T-shirt. Besides, it was rather hot and sunny. They'd dry off quick enough.

Both smiling, without removing the rest of their clothes, they walked to the edge of the pool and slipped in.

'Come on, Nico! It'll be fun!'

Percy pouted at the younger boy.

Nico shook his head.

'Nah, I'm not really fond of the water anyway.'

Hazel smiled deviously, an odd look on her.

'He's meeting Will in half an hour and he wants to look good for his date, not sopping wet.'

Nico turned rather red.

'Hazel! It's not a date, we're just hanging out. Soulmates can just hang out with each other!'

From the looks on all of his friends' faces, they didn't believe him.

Emily Zhang smiled as she examined a photo that Frank had sent her.

It was of him, Hazel, and all of their friends, enjoying a sunny summer's day by what she was pretty sure was Piper's pool.

Her son (he had grown up so much while she was gone...), in a T-shirt and board shorts, was standing on the left side of the group, with Hazel (she really couldn't wait to meet her; from Frank's emails, she'd gathered that Hazel was a lovely girl and had been very good for him), also in a T-shirt and shorts, on his back. Both of them were grinning.

Annabeth and Percy (oh, their relationship was such a story...) stood side by side, his arm around her waist. Percy wore blue board shorts, of course, while Annabeth was in a modest blue and white striped bikini with a sarong. She also appeared to be jabbing an elbow into Percy's stomach, while he had his mouth open, doubtlessly saying something stupid.

Piper, in a green bikini, and Jason, in purple board shorts, were standing next to Percy and Annabeth. They actually looked like a normal teen couple, arms around each other's waists.

Reyna, in a purple one-piece, sat on the left side of the photo along with two boys that she'd never actually seen before. The dark-haired, pale one in the black T-shirt and shorts was Nico, certainly, while she was pretty sure that the blond tanned one in the yellow and red Hawaiian board shorts forcing sunscreen on Nico was Will, Nico's soulmate. (Frank had mentioned him in his last email.)

On the right side of the photo sat Leo, in flame-adorned board shorts, bickering with an exceptionally beautiful girl in a white dress, with a red bikini clearly visible underneath. Emily thought for a moment; this was Leo's soulmate, the girl with the really strict parents (oh, the plans that Frank told her his friends had concocted to 'rescue' her...she hadn't laughed so hard for a long, long time...). She had an unusual name...oh, Calypso. Her name was Calypso.

Emily smiled, allowing herself to reminisce about her son and all of his friends, to imagine what they might be up to.

She logged off the computer, and stood to return to duty.

She would see them, see Hazel, see Frank, soon.

Her deployment was almost over.

And they definitely had a lot of catching up to do.

Things had changed, for the better.

Besides, she thought, grinning, her son, her little baby elephant, had found his soulmate. He'd found love.

What mother didn't want to be there to see that?

AN: I have this weird headcanon in which Emily refers to Frank as her baby elephant. Firstly because of the whole shape-shifting thing, secondly because Frank is kind of like a baby elephant- clumsy, awkward, unsure of his own strength and absolutely adorable!
