Rise Donnie

You were Donnie's girlfriend/boyfriend, you were previously from Canada but you moved to New York for your father's job, Donnie knew that

• Although Donnie is the most incredible genius of all, he did not know how to speak French, he only knows the basics, unlike your very advanced French, which you took advantage of to make a joke *

Donnie was calm, until you yelled nice things at him in French, he looked at you scared and confused, thinking you were scolding him "uh?"

You and Donnie were a couple a year ago, you were alike, that's why Donnie was interested in you.
Donnie, although he is the smartest of his team, doesn't know much French, only the basics, not advanced. Therefore, you took advantage of this to say nice things to him in French and believe that Donnie will think that you were scolding him.
