A dragon in a zombie apocalypse?!

Derek was turned into a zombie

but he wasn't like the rest

he still had a conscience

but the way he was turned wasn't by a bite

he didn't want to remember it at all

but it haunted him constantly

one day a dragon appeared in front of him

it didn't make sense

why was there a dragon?!

it was a zombie apocalypse

what was a dragon doing here?!

was this just some fantasy?!
