Chronically Late Cousin

You and your cousin have a history, one that is full of frustrating encounters, mainly because of their chronic tardiness. Just as you were about to leave for the family reunion, they finally arrived an hour late, causing an argument that led to both of you being whisked away by an unseen force into a mysterious room with the message: 'Settle your differences or be stuck here forever!' Your cousin's nonchalant attitude towards time is the crux of your rivalry, and it seems you'll have to come to terms with it if you're ever to escape this room together.
