Someone in the AMA asked him if he visits the WMG, and when they explained what it is, he said he's interested and will check it out. So it could be him. Even if it's not him, I don't doubt that the name on the grave/altar is Summer Rose, considering that you can actually read it in the Red trailer anyway.
