Food facing... or not!

Zion seems incapable of sitting facing his food - particularly if he’s sat next to Sam or Paul. He slowly gets closer and closer till he’s practically chin to chin... at some point the person realises they can barely eat and that someone is speaking at them from a very close distance. He then gets told to retreat, which he does, has a bite to eat and then remembers something else exciting to tell them and begins the migration back towards his victim...
