Friends and Lovers

S1, E10: Charles and Gwendolyn decide that college itself puts enough pressure on them and they do not need the additional ones of a serious relationship. There will be plenty of time for that once they have graduated. Charles explains to Stan and Jill Pembroke that, since they are so secure in their relationship, it will only help them appreciate each other more if they go out with other people. Then Gwendolyn has to cut her chemistry studying time with Charles short because she has been asked out on a date that evening. Charles begins fighting the first symptoms of a very serious jealousy attack.
