I really don't see Sona fallin for Issei. Like B214 said, there has been plenty of time, and there haven't even been hints of something like that happening. And Issei is too much of a nice guy to go after her knowing how much Saji likes her. There's also the problem that her and Rias are the next heads of their houses and both being with Issei would bring serious complications. And with Issei and Saji being friends, why would Issei fight Saji for her with him having as many women as he does and Saji having none?
