William: he behaved like that due to some reasons
Emma: :/
William: Maybe you should say sorry to him
Emma: Why should I?
William: You were supposed to invite him too
Emma: Maybe you are right

Emma didn't invite Ethan to the party, but someone informed him about it. Emma will say sorry to Ethan later.
