Sheldon在餐厅不小心喝了Leonard喝过的水，又用了他用过的餐巾，反应过度的他激动得去酒精消毒。Howard的老妈和Bernadette见面，Howard很担心状况，回家隔着厕所门问他妈如何，又告知对方他们订婚了，结果没有回答，只有咚的一声——老人家摔在地上了。Howard赶紧撞门，胳膊还撞伤了。
大家得知后赶紧赶往医院，Sheldon很犹豫——他害怕医院的细菌。Penny用超级英雄的话激他，他才勉强跟来。去洗手间出来时遇到有人咳嗽，他一下子躲到一个房间，结果那里是高危病室，这下子，他感染致死细菌，被隔离了……
Howard告诉Bernadette老妈可能是因为得知他要和她订婚受刺激心脏病发作的，Bernadette非常内疚，结果老人家还要见她，她很忐忑地过去了。去了才知道其实Howard老妈很喜欢她，根本不是Howard想的那样，于是她出来后痛骂了一顿Howard。
Priya和Penny一起去买咖啡，顺便聊了Leonard是前戏小王子的事儿。Raj也敲打Leonard透露了一些，还表示会告诉Priya，一副贱贱的样子。
