After Wilton Knight's passing, Elizabeth remained involved with funding the Foundation. A year and a half after Wilton's death, she invited Devon Miles to a friendly dinner date. Although Devon distrusted her motives, he attended. Elizabeth then poisons Devon during their meal in an attempt to obtain the formula to K.I.T.T.'s Molecular Bonded Shell.
Thankfully Elizabeth decides not to harm Devon, and lets him go. Soon, Wilton's criminal son, Garthe Knight - who had been in an African prison for four years - turns up in the United States. As it turned out Elizabeth had helped Garthe to avoid his life sentences by bribing a top official with leases on diamond mines. The official died not too long afterwards, no doubt thanks to Elizabeth.
Things get however complicated when Michael Knight gets involved. Elizabeth also plans to wreak her own revenge on Michael, believing he was trying to take her son's place. Elizabeth and Garthe intended on getting some missiles out of a highly guarded facility called "Red Bluff" using a massive semi truck known as "Goliath" now protected with the same indestructible molecular bonded shell technology as K.I.T.T.. Garthe uses Goliath to attack Michael and K.I.T.T., seemingly taking them out of the picture. Michael surprises Elizabeth and Garthe when he shows up alive and intercepts Goliath before General Kuna uses it to break into Red Bluff. Both Elizabeth and her son are arrested.
Sometime later, Garthe is freed from prison. When speaking with his new partner Adrianne Margeaux, Garthe indicates that Elizabeth passed away while she was still incarcerated.
