Darrel

Darrell is a minor character on the sixth season of Glee. He first appears in the third episode Jagged Little Tapestry, as Becky Jackson's boyfriend.
He is portrayed by actor and singer, Justin Prentice.
Jagged Little Tapestry
Darrell is first introduced by Becky Jackson when she comes home to introduce her new boyfriend to her family and friends. According to her, Becky did not start the relationship with honesty; telling him that she was president of every club in high school—including glee club.
When Sue Sylvester, Quinn Fabray and Tina Cohen-Chang realize Darrell is a normal and handsome guy, they quickly assume he is merely taking advantage of Becky and interrogate him with Roz Washington. When they ask whether they had sex yet, he replies no because their relationship hadn't gotten to that point yet, but blurts out that it may, which immediately engrosses the women, causing Darrell to question their motifs and beliefs. He tells them that just because Becky has Down Syndrome doesn't give them the right to judge her will to live like any other person, turning the tide around before he left.
In a glee club meeting, Darrell watches Becky perform So Far Away with Tina and Quinn hoping to impress him, but she quickly rushes out of the room. At the end of the episode, Becky comes clean about her lies, to which Darrell says he already knew because she exaggerated, but chooses to be with her.
The Rise and Fall of Sue Sylvester
He is seen back at Sue's office while accompanying Becky when she comes back to protest over Sue's unfair actions against the Warblers. Since Becky is yelling, Sue can't work out anyting that she says and thus Darrell is forced to clear it up. This shows he seems to understand her a little better than the rest of the people.
Darrell is by Becky's side during her appearance in a clip at Geraldo Rivera's TV program. Becky claims that she is happier than ever before because she is free from Sue and Darrell is with her. He is shown pushing Becky in a hammock.
