Ember 2.7 model inheritance, how to access the data from a sort-of-sibling (ie. another model my parent)

In Ember 2.7 assume you have a Person class that has an Address model (just assume city:DS.attr() is the only attribute).

app/models/person.js

import DS from 'ember-data';

export default DS.Model.extend({
  firstName: DS.attr(),
  lastName: DS.attr(),
  fullName: Ember.computed('firstName', 'lastName', function() {
    return `${this.get('lastName')}, ${this.get('firstName')}`;
});

An Employee inherits from Person and adds a status field (like hired, retired, fired, etc.)

app/models/employee.js

import DS from 'ember-data';

import Person from '../models/person';

export default Person.extend({
  status: DS.attr(),
  statusCode: DS.attr(),
});

In a component that is displaying the Employees, like this:

app/templates/components/employee-list.hbs

<div>
  <h2></h2>
  <p>Home Base : [WHAT GOES HERE TO DISPLAY eg. person.address.city?]</p>
  <p>Status : </p>
</div>

So how can I access the address of this Employee (ie. this 'Person')?
