Jenny.
Can you deny that you're in love with her?
Basil.
You're simply mad. Good heavens, I've done nothing that could give you the least cause to be jealous.
Jenny.
[Passionately.] Will you swear that you're not in love with her? Swear it on your honour?
Basil.
You're mad.
Jenny.
[With growing excitement.] Swear it. You can't. You're simply madly in love with her.
