 Discussing the workplace flirtation between Will and Emma , Gilsig deemed Terri " a woman of conviction " , willing to do " whatever it takes " to keep Will from leaving her , " even if that means finding this woman and hunting her down " . She explained that Will and Terri 's communication is weak and that Terri is " missing a lot of the skills for the marriage " , and commented that Terri feels threatened by Will 's commitment to the glee club , worried that it will pull him away from her . Gilsig characterized Terri as emotionally still being in high school , and explained : " I think Terri still lives in that world , where I can move the pieces in such a way to create a picture , and that will make it real . I don 't think she 's learned that you can actually just have open conversations and talk about your fears and ask for your needs to be met in a direct , compassionate way . I think she 's still in high school and thinking whatever you do , just don 't let anybody know that you don 't know what you 're doing . " Discussing Terri 's relationship with her sister Kendra , Gilsig commented : " When Kendra tells Terri to do something , Terri does it . As crazy as Terri might be , she 's actually pretty normal in the face of her sister . This [ fake pregnancy ] is Kendra 's brainchild , and she just trusts her implicitly . "
