Take a look: Here's your first glimpse of Glee's Grant Gustin (Sebastian) in his new TV role on CSI: Miami. It's only for one episode, so we don't expect Sebastian's screentime on Glee will be affected at all... but how awesome do Grant (and evil Grant!) look in this promo vid? So excited to watch!
