Well, yes this is a Gundam/Clamp series, we know eventually there is going to be some sort of healing unless Suzaku just finds out that Lelouch only wanted him to live after Suzaku has accidentally put his hand through Lelouch's chest and while dying Lelouch whispers "boku wa.. kimi wo.." XD;

Nannally isn't in Ashford and it's unclear from episode 25 who, if anyone did the rescuing. I mean while Lelouch considered her needing rescuing, Suzaku might not think VV is going to hurt her, it's not like she is tied up a la Mao. For Suzaku to think Lulu brought her back to Ashford he'd have to be the one who got injured pretty badly and Lelouch would also have to be sort of injured so he can't go get Nannally either.
