Disclaimer: I do not own Percy Jackson and the Olympians!

Leo POV

''Coming,'' shouted Andromeda, running to the door. Can pregnant women run? Damn the ADHD!

''What do we do now man?'' I asked Dennis. ''Do we run or hide or fight or what?'' Call me crazy for asking this question but after meeting a very irate Andromeda, I was not exactly too eager to meet her siblings. Don't get me wrong. I have nothing against Percy or Annabeth but I am not too eager to meet a version of a very angry mixture of both of them. I mean, I have seen how terrifying they can be in battle. Not to forget Percy's water powers. What will his children do if they do not like me? Douse me with salt water from the Pacific? Pulverise me with a sword? Shoot deadly arrows at me? Try to kill me in my sleep? The possibilities are endless.

However, apart from all this, I was really glad that Percy and Annabeth had obviously not died in Tartarus. I mean, they were obviously alive and happily married with four children. With a grandchild on the way! Hey, wait. Dennis is saying something.

''Don't worry about Charlie and Silena. They are cool. Just don't engage in gambling with them or you will lose all your money. Apart from that, you will be fine!''

''They sound exactly like Conner and Travis'' murmured Beauty Queen.

''Also Chris,'' added Nico. ''What?'' he added on seeing us glance strangely at him. ''Just because he appears innocent, it does not mean he actually is.''

''I agree,'' laughed Dennis.

Okay, I have changed my opinion. This is so cool! I mean not the part about a daughter who is ready to impale you with a sword at a drop of a hat, but Charlie and Silena sound really cool. I mean, twins ready to rip you off in addition to having cool water powers! What is there not to like. I am pretty sure I could help them pull off quite a few pranks. Fire and water...the possibilities are endless.

''Er...Leo, you are on fire.'' Said Frank cringing.

''I know man, I always am.'' I replied absently.

''No like literally ON fire!'' said Hazel pointing to my hair.

Sure enough, my hair was on fire and my clothes were smoking. This is SO not fair! I mean, it is not like Jason randomly shoots lightening or Nico accidently summons ghosts and skeletons when he is excited. Why can't I control my powers? Every else can! Anyway, I extinguished myself just as Andromeda entered the room her siblings behind her. Wait, this is not right. There are not three people behind her, only two.

''Wait, why are there only two people with you Andromeda? I thought you had three siblings.'' Damn my stupid ADHD! Now everyone is staring at me. Not that the two people (who were a boy and girl by the way) looked very threatening. However, why are they staring at me like they have seen a ghost? It is not like I am from the underworld or something! That is Nico.

However, before I could question them about their strange behaviour, they turned to me with identical grins on their faces.

''Leo Valdez!'' said the girl (I think her name is Silena?)

''We have-''

''heard so much-''

''about you!'' they concluded.

Great! The double act! They seem to have a pretty good sense of humour. I guess that settles it. We are going to be great friends.

''Knock it off guys!'' laughed Andromeda. Why were her eyes so guarded as she turned to twins like she was trying to tell them something important? ''You already know everyone. Meet the thirty two year younger Jason, Leo, Piper, Frank, Hazel and Nico!''

''Pleasure to meet you all.'' Said Charlie pompously, shaking our hands. Hey, wait a second. WHERE DID MY WATCH GO?

''Where is my bracelet?'' asked Piper incredulously.

''My skull ring is missing too!'' yelled Nico.

''Here,'' said Charlie grinning. Our 'lost items' in his hands. ''Okay, okay sis, I am giving it back, I was just kidding.'' He said looking warily at a glaring Andromeda. I swear that girl is more like Annabeth every second. He threw back our articles. ''You know I do this whenever anyone new visits.''

''I know'' said Andromeda through clenched teeth. ''It does not mean I must like it though.''' Man, she needs to take it easy. Dennis on the other hand must have broken a rib trying not to laugh.

''Chill sis,'' said Silena. ''I'm sure they do not mind too much, do they?'' to us she said, ''this is kind of a welcome ceremony of ours. We see if a person is alert enough to notice his or her belongings are missing. Until now, Dennis has been the only one who has noticed. That's how we concluded he was worthy of our sister!''

Oh yes, Dennis' father Chris Rodriguez is a son of Hermes after all. That explains it!

''Who taught you how to steal so proficiently?'' asked Nico curiously. ''Neither Percy nor Annabeth can steal to save their lives. Well, maybe Annabeth a little, but not so well.''

''Ever heard of the Stoll brothers?'' asked Silena. ''They are the ones who taught us. Mainly Uncle Travis actually.'' Was it only my imagination or did Silena hesitate a moment over there? ''Anyway, allow me to introduce myself. I am Silena Zoe Jackson and I am twenty one years old. I am majoring in Greek Mythology at Harvard where I hope to be Professor after graduation. Also, as you may have guessed, I am twin of Charlie and am the youngest in the family.''

''I am Charlie Theseus Jackson, also twenty one, twin of Silena and am majoring in marine biology from Stanford. Also, I am the best prankster at Camp Half Blood.''

Silena slapped him. ''That's MY title idiot!''

Yes, I definitely like them.

They both looked very similar with blonde hair which was much darker (almost black) at the roots and grey eyes flecked with green. Also, add the fact that Silena's hair was nearly as short as Charlie, and you had the ultimate double act.

Jason POV

Wait, wasn't Silena, I mean the original one a daughter of Aphrodite and Zoe Nightshade a lieutenant of Artemis or something? I doubt Zoe and Silena had ever seen eye to eye. Trust Percy and Annabeth to name their daughter after two polar opposites.

''Where is Luke?'' I asked. Hadn't Andromeda mentioned something about a third sibling? The very next instant, I wished I hadn't. Silena and Charlie grinned at me with identical smirks that spelt T-R-O-U-B-L-E.

''I thought you would know Jason,'' said Charlie innocently in a manner that made me suspicious immediately.

''He is with Alexandra, his girlfriend. They are going to meet us at Uncle Nico's directly, Andromeda.'' Added Silena. ''He asked us to inform you about it.''

''Do I want to know who Alexandra is?'' asked Piper cautiously. Gods, she looks so cute.

''Piper,'' said Charlie theatrically, clutching his chest

''how can you-''

''not know-''

''your own daughter?''

Again the double act. I swear, these twins could give Conner and Travis a run for their money.

''Wait a second, Piper has a DAUGHTER?'' I exclaimed.

''Oh, don't worry Jason, she is your daughter as will.'' Said Dennis. ''To be honest, you are really overprotective about her. So much so, that Luke and Alexandra waited nearly a year before telling you they were dating.''

What? I am an overprotective father? Moreover, I have a daughter with PIPER? I could feel my face heating up. So was Piper's.

''I thought it would be impossible for a face to become this colour.'' Laughed Andromeda. Not like the others were any better.

''Jason and Piper sitting in a tree...'' sang Nico, Leo, Silena and Charlie. Damn them!

''Shut UP guys!'' I yelled. This just made everyone laugh harder.

''Okay, that is enough. Lay off!'' said Hazel. Thank the Gods! At least there is one mature person here.

''How-how is Luke?'' I asked cautiously after the laughter had somewhat died down.

''My kid brother's alright, don't worry.'' Said Andromeda, her eyes twinkling with mirth. Great, no sooner have I learnt that I have a daughter than I have gone into overprotective father mode. ''He's twenty three and an architect. He takes after mom, you know. In his appearance, he looks like a typical Athena kid with black hair and grey eyes. Also, he is the brains of the family.''

''Not to say that Andy is not intelligent. She is the chief editor of the New York Times. As for Charlie and me, we just choose to use our intelligence in a different way.'' Smirked Silena.

''By playing practical jokes on people. Not to mention invading their privacy.'' Groaned Andromeda, shaking her head.

''Now, now, Andy, it is all harmless fun.'' Said Charlie.

''You mean like how Silena thought it would be fun to dunk Dennis and me in the lake at Camp last summer?''

''Aw, you survived. Isn't that the most important part?'' said Silena, completely unapologetic.

''DENNIS CANNOT BREATHE UNDERWATER!''

''You can though, can't you? You easily saved him.'' she got her there, I have to admit. Looks like all of Percy's kids have great debating skills. They must have got that from Annabeth.

Andromeda looked outraged. Her face told me only one thing – payback.

I glanced at Leo. His face was one of a person whose wildest dreams had come true. Mental note – don't let Leo go pranking with Silena and Charlie. It is a recipe for disaster.
