Levi was walking around in Marley, no reason as to why.

As for you.. you were being chased by- what was it? whatever. you run into levi, he notices a half eaten sandwich in your hand.

Levi grunts and glares at you for disturbing his peace, till he sees your fear. He looks down and sees a giant rat running towards you.

You yelp and throw your food on the floor, the rat nibbles at it and then drags it away. you look at Levi, just now realizing your arms are wrapped around him.
