I dare Jack to run to North Pole and leave a note saying that he not like Merida anymore but comes back. (The person has grammar error,lol)
Jack:I am definitely gonna be crushed by her..but okay,lets do this!-writes the note and runs to North Pole-
Merida:Jack?Where are you,dinner is served!-sees the note and reads aloud-"Dear Merida,i am leaving because of all the dares and pranks you have done to me.I think we should break up.Goodbye...Love,Jack Frost."Jack?
While in North Pole...
Jack:-watching Merida cry-Oh god..Haha!-goes back to Merida-Surprise!
Merida:You!!!How dare you,gramps!
