Another story which takes place during the events of "Life without Penny". The story starts just before the end of "A year in the life of Leonard Hofstadter" and ends at the start of "The Cooper-Winkle Relationship Transition."
######################
December 16th. Leonard called his wife Leslie by Skype from Princeton.
"Hello Leslie"
"Hello Leonard, how is your sister."
"She gave birth to a son 4 days ago, my nephew is called Scott."
"I see, when are you coming home."
"I am home Leslie, I am staying at Princeton. I have accepted the Professor job here."
"Oh really."
"What about all your stuff here."
"I made sure I brought all my really important personal things with me. The rest is all in storage. Anything else in the apartment you can do whatever you want with."
"What about your precious Comic Books."
"They are just pieces of paper, do what you want with them. I want a divorce Leslie, I am sorry. My lawyer will be in touch. If you need to contact me I am staying with my mother. Goodbye Professor Winkle."
Leonard ended the connection.
Next he called Sheldon.
"Hello Uncle Leonard."
"Hello Sheldon, I have some good news and bad news."
"What is your news Leonard."
"I have accepted the Professor job here at Princeton, effective immediately. I am not coming back to California. I have just told Leslie that I want a divorce. I have some boxes of scientific books and papers boxed up in my office at Caltech, could you please arrange to have these shipped to me at Princeton, send them to me care of my mother."
"Oh Leonard, what have you done."
"I am making a clean break of it, we should never have got married. I think I agreed to marry her to get away from having you as a roommate, not a smart move."
"I see. Well congratulations to you Professor Hofstadter, good luck for the future."
"Thank you my old friend, keep in touch, I now need to break the news to Gablehauser..."
