This is more than half joke. I didn't just wanna write a filler chapter and this plays into the fourth-wall break idea brilliantly (if I do say so myself). Rest assured, you'll get a real chapter soon enough.
Long Travel; Short Chapter.
Nothing happens on the trip from Camp Half-Blood to Camp Jupiter. Kinda anticlimactic after last chapter's 'jinx' dialogue, but what can you do?
Literally the most eventful thing that happens is Mrs O'Leary giving me a solid stereotypical doggie greeting and me having to scrub the saliva off. So I'm gonna summarise the trip for ya.
As per Cabin 6's plan Uncle Nico thrice shadow travelled us the maximum distance he could in one go, taking twenty minutes to recuperate each time. He spent thirty minutes total instructing me in Underworld Basics, while Dad took the ten remaining for my Poseidon training. To everyone's relief and confusion, I am still unable to summon Zeus powers and didn't even summon them accidentally.
Mrs O'Leary met us somewhere in Nebraska. She's unchanged, bounding to Dad, then Uncle Nico, tackling them both and giving them a warm and wet welcome. She then sniffed me, looked at Dad for confirmation, and gave me the same treatment. Thankfully my water magic is good enough that I was able to summon some water to wash myself.
Mrs O'Leary shadow travelled in two straight jumps without down-time, apparently more adept at it than the King of Ghosts, and got us to our destination just after nightfall. Which should remind you that all the events in this fic up to this point have all been within twenty-four hours. My life has been redesigned and the day's not over yet.
Anyway, Mrs O'Leary got us just inside the entrance to Camp Jupiter, the one Misted to look like a maintenance tunnel. She ran off toward the camp proper below and currently we three—though it's mostly just me—are staring at the prosperous city and militarised camp in the valley.
TL;DR: Uncle Nico, Dad and me (and later Mrs O'Leary) shadow travel from CHB to the Romans.
See you in the next chapter.
