Destroy your son

"If he does not join us, I will destroy your son."

- Emperor Palpatine

Destroy your son was a favorite threat of Darth Sidious, having first used it against Darth Vader to destroy Wormie, and later against Han Solo and Leia Organa Solo to destroy Anakin Solo. Both times, Darth Sidious died.

The Solos have also noticed that Wormie likes to destroy their sons.
