Samuel Reyes a.k.a. Grandfather Timeline and Summary

Grandfather's eightieth birthday and Final Banquet occurs two days after Cassia's Match Banquet.
Grandfather receives a tissue preservation kit from the Committee, meaning his status has earned him eligibility for tissue preservation—if Society figures out a way to bring them all back to life someday, he's golden.
For his final feast, he chooses all desserts.
Upon receiving Cassia's final gift of copied and pasted sentiments, Grandfather advises her to trust her own words.
Grandfather takes a final look at a piece of paper he's got hidden in his compact, and gives it to Cassia to understand later.
Grandfather dies right on cue, and his last words are "'I love you'" (7.99).
