'against my will' - double meaning?
Ok, I just have to ask: What the hell was the double meaning that Benedick sensed there?
edit: Maybe to be more precise: Beatrice was sent to fetch Benedick for dinner, after he already heard the staged "Beatrice loves Benedick" conversation. She says something along the lines of "against my will, I was send to fetch you for dinner". After she leaves, he ponders her wording and suddenly realizes "against my will - there's a double meaning in that".
It has always bothered me, what that second meaning is supposed to be. Is it a joke by Shakespeare (i.e. there is no double meaning, but Benedick is so enamoured with Beatrice that his mind plays a trick on him) or am I just not good enough at English to find it?
