August 2047. Professor Sheldon Cooper was dead. At Sheldon's non-religious memorial celebration at Caltech, family, friends and scientists from all over the world had come to pay their respects. In the front row of the auditorium, with Sheldon's grieving widow Amy, were Raj, Howard, Bernadette and Leonard. Next to Leonard in her wheelchair was Penny. Raj was now back in India as Professor of Astrophysics at Delhi University. Howard and Bernadette both worked for NASA in Texas. Leonard and Penny had both moved back to Penny's home town in Nebraska when Penny had to retire due to ill health 5 years earlier.
The penultimate part of the celebration was President of Caltech talking about Sheldon's very distinguished scientific career, including winning the 2030 Nobel Prize in Physics. After she finished speaking the celebration ended with a recording of Sheldon playing the "Star Trek" theme on the Theremin.
Afterwards, while Penny was chatting with Sheldon's sister Missy. Amy took Leonard aside for a private talk.
Thanks to both of you for coming all this way. How is Penny doing?
Well she has good days and bad days. It was quite a challenge getting her here but she was determined to come and "say goodbye to Moonpie."
How much help do you get with her?
Well a nurse comes in every day, and some of Penny's nieces and cousins lend a hand. I am still able to teach at the community college a couple of days a week.
I suppose this is not how you planned your retirement together?
No but you know, "for better and for worse", on the whole we have had a wonderful life together.
Amy gave Leonard a hug and said "look after my bestie."
