You were babysitting Bonnie. This took several hours of convincing Clemont that nothing would go wrong while she was with you.

This happened.

You were not the one who fornicated with her, and you know that she did not fornicate with anyone else while you were babysitting her as you were with her the whole time. However, Clemont will automatically assume that you did it because he hasn't seen her banging anyone, so he will assume it occurred while she was with you.

How do you convince him the child isn't yours, and that nothing uncivil happened while you were sitting for her?.
