Sebastian

Sebastian Smythe is a character from Glee

The First Time
Sebastian first appears in the fifth episode of Season Three, The First Time, during the Warblers' performance of Uptown Girl. Upon seeing Blaine, Sebastian takes immediate interest. Immediately following the song, the two are shown speaking at a table in what is assumed to be Dalton's cafe. Sebastian indicates that Blaine was a "legend" amongst the students at Dalton and was described as "sex on a stick and sings like a dream", and asks why Blaine decided to transfer. The scene is intercut with Santana and Rachel 's performance of A Boy Like That, suggesting Sebastian's promiscuity. Blaine seems uncomfortable and flustered by his advances, however, he agrees to see Sebastian again for more "insight... Warbler to Warbler".They later visit the Lima Bean, where Sebastian continues to proposition Blaine. Blaine responds by explaining that he has a boyfriend and does not wish to ruin that relationship. They are interrupted when Kurt himself enters the scene. It is clear that Kurt feels threatened by Sebastian's desire for sexual relations with Blaine. Sebastian, after suggesting that their relationship is unexciting, invites them to visit the gay bar Scandals with him. Blaine initially declines the offer, but Kurt is quick to decide for the both of them that they will go.Sebastian manages to get them all fake ID's. Kurt and Blaine meet him at the bar, and Kurt admits "I really don't like that guy." Sebastian gives Blaine a beer, and Kurt, the assumed designated driver, a Shirley Temple. While Kurt and Karofsky are having a conversation, Sebastian dances with Blaine.

Hold On To Sixteen
In Hold on to Sixteen, Sebastian approaches Blaine and Kurt at the Lima Bean, stating that he had recognized Blaine by his hair. Blaine congratulates him on the Warblers' win at their Sectionals, and Sebastian assures him that Blaine is capable of whipping the New Directions into a "legitimate threat". Blaine abruptly leaves for more coffee, leaving Sebastian and Kurt alone. After each bluntly states their dislike for the other, they trade insults, culminating in Sebastian revealing that by the end of the year he plans on having Blaine and the Nationals trophy. He calls New Directions a joke too. Blaine returns, oblivious, and Sebastian takes his leave, advising Kurt to "take care of that Warbler". During New Directions' Sectionals performance, Sebastian is seen in the audience cheering on Blaine and giving standing ovations. At one point he makes eye contact with Blaine and Kurt, eliciting a negative reaction from the latter. However, the standing ovation might mean that Sebastian might not find New Directions a joke and is impressed by them.
