I wonder if Horizon might have a second heroic identity that she uses with our team, that her family doesn't know about? Perhaps that's a way to be a superhero on her own terms and follow her own ideals rather than those established by her family. Just an idea :)
That might be a bit much for the poor girl. ^^;
My plan with Horizon is that her being on a superhero team of her own isn't an issue at all. If anything, it might have even been encouraged by her family to get her some practical, "boots on the ground" experience, and she might even be expected to take a leadership or advisory role within the team itself. On her own, Horizon is already a superhero; a well-known one at that. Her association with the Astro Team is such that any screw-ups that occur while she's on a smaller start-up team would be swept under the rug for her in a bit of superheroic nepotism.
I should expand on what I was planning for her family as well. The Astro Team I've mentioned so far is supposed to be a play on the Fantastic Four in terms of their overall relevancy and level of power/influence in the setting. Big family full of superheroes, all of whom operate under the same umbrella. While a few of them are the "fighting the monster of the week" types, the majority are more science and humanitarian heroes; the kind that use their various powers to further scientific progress, perform civilian-focused services, address natural disasters, etc. A less combat-focused type of hero. Overall the Astro Team family have a lot of influence, a lot of wealth, and a
ton of good will from the general population.
Horizon being brought up as yet another member of the team was a forgone conclusion. It'd be a standard practice among the family that all the younger "in-training heroes" would undergo various tiers of education to help in their upcoming career (civics training, law, the sciences, etc), get some practical experience in using their powers for the greater good (as a crime fighter, or some other non-combat end), and then eventually be cleared to join the Astro Team full time. At the time of this game's events, Horizon would be in the middle of that period of her training; the better she performs with the party of young heroes, the more likely she is to be put on the Astro Team sooner than later. Which leaves her in this terrible spot of knowing she can't just shirk her duties and drag her heels because that would endanger others and get the party in trouble. But doing a good job shortens what little freedom she has left and makes it harder for her to have any individualism.

My idea is that her parents sent her away to a special boot-camp/boarding school for troubled young supers to keep them safe and help them fit into society. The problem is that this place is run by an anti-superpower organization, and the curriculum is designed to suppress the kids' powers and force them to be "normal"! Daisy's parents chose this place because they're suspicious of supers and view them as dangerous, and of course the accident only supported that belief. They sent her to the camp so they could have a "normal" daughter :(
I like the concept of this kind of boarding school. Depending on how prevalent spontaneous super powers are supposed to be in our setting, there might be a lot of these kind of places with varying attitudes and approaches on how to handle supers. Daisy's parents just picked one of the bad ones.
It might even be the case that the "bad" schools, like this one, are literally bad. As in, founded or sponsored by super villains in an effort to suppress the rise of a new generation of heroes while also sifting for potential villainous talent. It'd be real easy for a villain to pick out a promising, easily-manipulated student from the batch and radicalize them into villainy. The usual "they're all trying to force you to be what they want, they don't understand you, they're scared and jealous of you" sort of spiel that's very tempting to an oppressed youth. It wouldn't surprise me at all if "Miss Informative" was on the board of trustees for that very same school, for example.
