Jeanne Tripplehorn Jeanne Tripplehorn

Jeanne Tripplehorn just wants you to like her — or her Criminal Minds character, at least.

The Big Love alum will return to TV Wednesday on the CBS drama (9/8c) as new BAU member Alex Blake, and all she can think about is what will happen after the episode is over.

"The fan base is huge for this show and I am honestly nervous about what they will think of Alex," she tells "A show bringing somebody new in on the eighth season, especially if you've been [a fan] since Season 1 — people will have their opinions. I think the fans are incredible and I respect this insanely rabid fan base the show has, and I do want them to accept Alex. I hope they like her."
