Kurt went to Blaine's college to surprise him, but he was at class or something, and ended up meeting some of Blaine's friends, who took Kurt to Blaine's room to wait.
Blaine had a wall in his dorm devoted to pictures of himself and Kurt if I remember correctly.
Also one of Blaine friends covered his eyes and directed him into his room, where Kurt was waiting.
Hope my tags are alright mods.
Also, if anyone knew of any other fics like that, recommendations are welcome. :D
