Hee, I figured if she gets resurrected ala Shiro, she would make a grand entrance for sure! Can't take the princess out of the paladin.

Lance, after all his development (up to S7 aka the last VLD season, cough) totally strikes me as a Real Men Wear Pink kind of guy who would puff up with pride at being the flower girl.

Keith absolutely would be that extra just for Shiro, and it makes me so happy! (Kosmo is the ringbearer in that wedding.)
