Is it possible to get the Parent of an arbitrary Entity?

[Newbytee]

I know I can query an Entity along with its Parent from a system like so:

fn example_system(
    pairs: Query<(Entity, &Parent), (With<...>, Without<...>)>,
) {
    // Function body
}

But what if I want to get the Parent of an arbitrary Entity from within a function body? Is that possible? Does it even make sense? I would like to do it for debugging purposes, but I am not very familiar with Bevy in general, so I don't know if what I'm asking actually makes sense within Bevy's design. Still, if it is possible, I would like to know how I could achieve it.

It is common and performant to use queries to retrieve components for a single Entity with Query::get.

fn example_system(parent_query: Query<&Parent>) {
    if let Ok(parent) = parent_query.get(entity) {
        // ...
    }
}
