 Overall , while fan reaction to her character had previously resulted in a backlash Gilsig found " tough " , she hoped that " Mattress " would be the episode in which " anti @-@ Terri fans joined Team Terri " . Asked how she felt about Terri being a ' love to hate ' character , Gilsig replied : " As long as you love to hate her , that 's OK . It would be a different show if there weren 't characters like Terri or Sue Sylvester ( Jane Lynch ) , otherwise you 'd be at Disneyland . It would be the happiest place on Earth . " Gilsig does not know how long her character will feature in the series , and has explained " When Terri was created , she was created obviously to be an obstacle between Emma and Will . They needed an obstacle , otherwise there 's no show . What 's been fun about it is that she 's managed to emerge as a character unto herself with her own complexities . "
