Aiba is choking on his soup mainly at the idea that anybody would blow Sho while he is actively mothering them (which is seriously his best stress relief. Jun talks seriously about getting him a baby some days).

I didn't know that Yoko was already forming his own group (in his head). :D He'd totally do Arashi+Yoko. Imagine all the fun they'd have! Imagine Ryo's face! Imagine Jun's! Imagine Ryo and Jun bitching together to hide their tears!
