Pepper's Ghost

The Pepper's Ghost effect has long been an illusion of the stage and other performances, conjuring the appearance of an ethereal spirit. It follows that it would play a role in the proposal of marriage for Dethany and Guy since, after all, what is more ethereal than the prospect of eternity together?
For that reason alone 2019 was a big year for Dethany, but other major events also occurred. Autocorrect and the Computer Bug became parents with the birth of Cora, and Ms. Trellis brought in a consultant to advise her on Fastrack's operations. Guy also made progress toward his Master's Degree research on the Internet of Things.
Dethany's sister Grace experienced a crisis of confidence, and on Valentine's Day we discover the true relationship between Cupid and Death.
What could be more transparent?
