Frank Zhang Regretted saying yes.
As soon as he said it, he regretted it, didn't see why they had to go to England of all places. Frank didn't understand why this wizarding school had to be in Europe, anyway. He would have prefered it to be in San Francisco. Heck, he wouldn't have minded had it been in New York. Frank had a whole list of places he'd rather it be, and England was nowhere on that list at all.
He has no Idea Where his dislike towards England came from. As far as he was aware, England had never done anything to him, he just didn't like it. Maybe it had something to do with him being canadian, since britain still technically owned Canada, But Frank didn't think that was the case. Nevertheless, he was not looking forward to going there.
He might have told Chiron that he had changed his mind, except he remembered that Hazel, despite her experience with witches in her previous life, had offered to go without hesitation. Frank respected her for that, and thought that if she could do it, he could too, and so, when the 10 demigods met Chiron up at Thalia's tree, he went with an open mind.
Chiron still made Frank a bit nervous, he always seemed to know just what you were thinking. Honestly, it was a bit unnerving, but Frank didn't say that outloud. If it was anything to go by, he didn't have to.
They had already been briefed on the details of the quest, but they were only told now how they were actually going to get to England, probably so that Chiron didn't have to have Percy, Nico, and Thalia bugging him the whole night, but rather to have them committed to the point of no return.
Frank didn't know why Thalia didn't want to fly in an airplane, her being in the daughter of Zeus and all that, And he certainly didn't want to ask her because, quite Frankly, Frank found her absolutely terrifying, so he let it be. Nico offered to shadow travel there, and Frank heard a distant "Not on my watch death boy!" coming from the Apollo cabin. If you asked him, Frank would tell you that Percy conveyed his point a lot better than he ever could in words, as he just glared at Chiron, as if to say Do you really want me to die? Chiron said that they had sorted it out with Zeus, but Frank thought that they all still looked on edge. Especially Thalia, who didn't seem at all relieved by the news.
The 10 of them hopped into one of the camp vans, and Argus drove them to the JFK international airport, where, by some miracle of the gods, they escaped having to go through security. The flight started uneventfully, but on a 7-hour flight with a bunch of ADHD demigods, somebody's gonna get bored. Frank didn't have a problem with the length, as he himself was not ADHD, and Reyna was used to long, boring, senate meetings, so she wasn't particularly affected.
He was worried about Valdez though. Frank knew first hand that when the annoying little imp got bored, something usually got blown up. However, when he looked at Leo, who was sitting next to Piper and Jason,who were watching some movie, Frank couldn't help but notice that he was only staring out the window, fiddling subconsciously with some wires, with a melancholy look on his face. Frank frowned and looked over at thalia. She was being consoled by a laughing percy, while annabeth tried to convince him to stop laughing because, as Thalia so angrily said it "this is no laughing matter". He didn't know what they were talking about, but Thalia looked pretty shaken up.
Nico was asleep, or so it seemed to Frank, who could never quite be sure about anything concerning the son of hades. Looking back down at Hazel, he figured that, however sucky his life has been leading up to this point, at this moment, it couldn't possibly get much better.
