when Kurt and Blaine are going to a concert where Blaine performs. Kurt is in the crowd while Blaine
is on stage and I think he overhears some girls talking about how awesome Blaines voice is.
After the show he waits for Blaine off stage and shows the girls that he belongs to him :)
Hope anyone knows what I mean.
I thank you for replays in advance. :)
