Marlon I can say is a determined soul. He might not have been as quick at getting something right away as Michael did, but he would work at it until he got it. He could put his mind to something and stay focused.
He did learn a lot from Michael as they were both very close in age. He is a great dancer, but was in Michael's shadow so the public never go to discover how talented he as a solo artist could be.
I recently watched him perform on stage with his brothers, and I could see the moves flow naturally out of him. I am happy to see him get the recognition he deserves.
