The relationship between Penny (Kaley Cuoco) and Leonard (Johnny Galecki) on CBS' Big Bang Theory hasn't exactly been without its share of tiffs, and it appears that season 7 will put the twosome in a somewhat similar predicament.

According to E! Online, Penny and Leonard will once again be experiencing rocky roads, as the entertainment site reported that the latter will still be away from his significant other to start the seventh installment.

"In the first episode back, we'll get a peek into Leonard's life, and let's just say that things aboard the ship are less about thinking and more about drinking. When Penny & Sheldon reach out to call their beloved experimental physicist, Leonard is making waves and partying it up with multiple ladies."

In the finale of season 6, Leonard went out to sea to embrace a once in a lifetime employment opportunity, meaning he would be apart from Penny for a period of four months. While the couple made the decision to stay together, the situation is set to be rough when the TV sitcom returns in the fall.
