When Ontario is in America trying to get DC, he encourages DC's workaholic habits 

Ontario's a workaholic himself 

"C'mon we're both governments, we should be working constantly." 

If DC tries to say that his boyfriends said he needs to take breaks, Ontario would just laugh and be like 'c'mon, they don't know what they're talking about, they're states'. 

DC finally passes out because he's stayed up late, barely ate, and only drank coffee 

California's like this close to punching Ontario when he finds out it was him who encouraged to do it 

Or maybe he does punch him

(Granted I don't think he was being malice, he was trying to prove that he was better than the states because he knew what work was just like DC. He was also shocked when DC collapsed, thought DC was used to it.)
