Here's Dani in her California living room.

Perched on her shoulder is little Hayu, fully locked in.

He's wearing a tiny yellow vest that reads, service animal.

Dani suffers from brutal muscle spasms caused by nerve damage.

Hayu's job is to feel the first subtle tremor before she does.

He licks her neck and she immediately takes action before the spasm knocks her flat.

A minute can make a world of difference.

He doesn't stand down until the danger passes.

Then finally takes a well-deserved break and a delicious snack.

Thank you for your service, Hayu.

Danny's saviour, the rat.

Rats.

They hit our food supply and unleashed biological warfare.

We hit back with nasty propaganda and almost every chemical we could get our hands on.

It's almost unthinkable to think we're related, but sometimes, just sometimes, we are in sync.

Welcome to Life Without, where I take something away from the sum of life, a constant in our equation, just subtract it.

With my powers, delete it.
