On a recent episode of the Edge & Christian Pod Of Awesomeness Rey Mysterio was the guest and it was a hell of a fun show.
One of the most interesting parts of the show was when they were talking about his son Dominic. Rey said that he is currently training with Jay Lethal in TNA, but he wants him to go all over the world and train and next he wants Lance Storm to train him in Canada.
Rey Mysterio also said that he would like his son to finish his training in Mexico with him, where when he is ready to hang up the mask his son would take it over. What a huge honor that would be for him, but even with his short stature, those are some huge shoes to fill.
