Jack and Wanda have known each other longer than most other units within Gobwin Knob. Both Wanda and Jack come from the Kingdom of Faq and turned to Stanley's side when he destroyed their native kingdom. While in Faq Jack and Wanda used to spend time together discussing the philosophy of magic, especially the subject of love, and it seems both Jack and Wanda were deeply attracted to Jillian. Jack doesn't seem to have been angry or bitter that Jillian favored Wanda over him. Wanda made a point while in Faq of using Jack's full name and title, suggesting that she wished to maintain a certain degree of formality in her dealings with him. Jack currently thinks that Wanda is a "vessel cracked worse (and repaired worse) than he," referring to Wanda's emotional and mental state, and may resent the fact that Wanda wanted to allow him to croak so that she could decrypt him. However, any concern he may have about her growing power didn't stop him from having some fun at Wanda's expense by pointing out that Jillian may now prefer Ansom over both Wanda and himself.
