>>1597866>I just have to know how in the world Grey can't want to tap that shit.It's implied (more subtly than just about any other potential pairing in the series) that Grey has a very well restrained crush on Erza.
With Ultear out of the picture, that makes Jellal the primary roadblock to Greyza. And that's a pretty fucking big obstacle. Don't expect Grey to hook up with anyone until Erza's relationship is sorted out.
