Leonard is away on the research vessel in the North Sea, and Penny and Sheldon are missing him. Sheldon doesn't really come out and say it - but he clearly is clinging to Penny for comfort. In the meantime Koothrapoli is now able to talk to women without booze, but he remains heartbroken over Lucy. He runs into Ms. Davis at a University event, and they learn that they are both heartbroken, as her husband just left her. Bernadette and Amy are at a conference out of town together, and they decide to visit the hotel bar, where some guys try to buy them drinks. Later, they chat about the type of guys they like - and they end up weirdly describing Sheldon and Howard - but Amy describes Howard as her type, and Bernadette describes Sheldon.
