2. Why was Lakunle so heart broken at the end of the book?

Suddenly Sidi runs in, sobbing. She throws herself to the ground. Lakunle is horrified and asks if she was beaten. Sidi sobs that Sadiku was fooled: the Lion tricked her and was not impotent at all, so he raped Sidi and took her virginity. Lakunle announces he will still marry Sidi.
