Breaking the Barrier

Twins, Natasha and Serenity Benson, are, were, as long as they can remember, and as long as they can care, misfits.
They avoid everyone because everyone claims that they are one soul, one mind, and one person.
When anyone tries to get to know them they first play a game called
'Which one is Natasha?'
They build barriers and build them as strongly as they can so no one can barge through.
So far no one has gotten in.
Until one loser, one idiot, one out of seven billion people, one person, breaks through.
And that loser, that idiot, that one in a seven billion chance, that ONE person's name is
Spencer Lutgen.
