If it’s Neal then it seems morel likely he’ll show up at some point in 522 (Only You).
Actually, if is Neal, which i dont believe at all, i would say 523 not 522, after 315, neal only appeared on episodes that A&E wrote, he may be mentioned in other writers episodes, but only appears on A&E epis, so if ends being Neal, would fit that A&E wrote a scene to be insert on 523, that was filmed in January, so if is Neal, he will appear on 523 and not 522. Only you would lead to one apperance on 523, which for me, would still be a bad use of word return, bc for me one scene means apperance and not return, but whatever.
