I'll add you to the on call list, but I prefer the wardens who are supervisors to keep their keys, and no others. It's so hard to keep track of them...

But then, what if one of our shift supervisors were to leave?

I'll offer a compromise, Miss Chandler.

[And congrats; you get a key, but it will only work when there is no shift supervisor present to let you in otherwise. Upon a shift supervisor disappearing, it will graduate to a 'main' key]
