Penny: "Sorry, sometimes I forget your smart because your so sexy."
Leonard: "That sounds about right."
I really liked this episodes even though it really wasn't Lenny centered. Seems like we will get that in the last few episodes. I'm not a huge Shamy fan but love when Lenny is there supporting their friends. The few scenes we did get of Lenny were so them. Penny sneaking on her phone so she could sound smart was classic Penny. But anyways here is my insight on what might have happened afterwards. By the way at the end it is up to your imagination what happens.
Continuation of 12x18
Penny went after Amy to the restroom to see if she was okay after her outburst. Leonard stayed by Sheldon's side not really knowing what to say or do next since Doctor Pemberton and Doctor Campbell left acting like nothing happened. Then Professor Siebert went off with the Nobel Laureates to discuss the whole situation. Once Penny had talked to Amy and calmed her down, they came out and each couple went their separate ways.
While in the short drive home, Leonard finally said something, "Um, so how was Amy?" he asked giving hos wife an uncertain look.
Penny turned he head with a small smile, "She is okay now but more embarrassed and worried she might have ruined their chances even more. I just gave her a hug and told her maybe things will work out since Doctor Pemberton and Doctor Campbell been exposed now and no matter what we are there for her and Sheldon. Amy didn't say much after that."
Leonard looked at Penny for a quick second and grabbed her hand. He then brought it up to his lips an kissed it. His eyes were back on the road as he held Penny's hand in his that now laid in his lap. "You know you are a good friend, right?" Leonard heard his wife's respond with a I try my best then he continued as he drove. "You are and never forget that. But anyways what would you like to do now the reception got over earlier than expected and we are dressed up? Your sexy smart guy is up for anything."
Penny let Leonard let go of her hand as he needed to use both hands now driving. But she left her hand stay on his inner thigh, which made Leonard swallow hard, which only made Penny smile big. She loved how she still had that affect on him. Then raised an eyebrow as an idea came to her. Penny sat up some to tuck her legs underneath her and leaned over. She then whispered into Leonard's ear.
Leonard almost couldn't believe his ears and he reacted by swallowing hard again but with a childish grin on his face. He looked at his wife once more as they came to a red light and suddenly putting on his turn signal the opposite way of thier apartment. "I am not opposed to that idea one bit." As he watched Penny's response he knew he answer was very satisfying.
