Margo Harshman Shakes Things Up on 'Big Bang'
'Bent' actress could drive a wedge between Leonard and Penny
Leonard and Penny's on-again-off-again love affair will experience yet another hurdle when "The Big Bang Theory" returns for a sixth season.
This time around, that "hurdle" will be named Alex, a character played by actress Margo Harshman of "Bent" and "Even Stevens" fame, reports TV Line.
Alex is Sheldon's (Jim Parsons) new assistant but soon after she meets Leonard (Johnny Galecki), sets out to make him hers, Penny (Kaley Cuoco) be damned.
Sheldon and Amy (Mayim Bialik) will also experience some relationship challenges this season. The trouble starts when Amy wants to get more serious and Sheldon doesn't.
"The Big Bang Theory" returns for season 6 Thursday, Sept. 27, at 8 p.m. ET/PT on CBS.
