He was exactly...who I had envisioned in the role. He got the part. During the next season he shared his story with me and I was so impressed with him. 1 year ago I got a text from @MagdaEh with the sad news of his passing. I sent blessings to him then and now. He was a good kid.  Sending positive thoughts to those who knew and loved him. I'm enjoying remembering him tonight."
