Why did she accompany Alassene even with all the dangers of being alone with a slave trader? 

After a few years of living in Freetown, Aminata is unable to make any progress in trying to make her way back to Bayo, her ultimate goal. After Temne rejected her request to take her inland, with the help of Alexander Falconbridge, she makes an arrangement to accompany a slave trader enroute to the inner part of Africa, where she can find her village. Even though it was told her that Bayo likely didnt exist anymore, she wanted to see it for herself. Why do you think she was so persistent? Why did she accompany Alassene even with all the dangers of being alone with a slave trader?
