It all goes back to that weird trip he took to see his secret grandmother that he said was sick and dying of cancer. Who really knows what happened to her. He went to get that BC out of the shoebox and anything else that was in that house relating to his past and billed it as a visit to his sick grandmother that no one ever saw.
He probably gave grandma a pillow...
Why draw attention by doing it himself? It would make more sense to have someone else that while he is conspicuously far away.
