I am so happy that I got to spend almost everyday with you on set, you gave the best hugs. I wish I would have hugged you tighter when I saw you a couple of months ago. Thank you so much for being the big brother I never had... I am so distraught and I cannot stop crying! I love you so much... fly high Gods best Angel [sic]."
