In November 2020, Justin started to hallucinate his former teammate Pat Dugan while searching for his long gone horse. Justin brought his sword to the Pit Stop and asked for Stripesy's help. However, his hallucinations started and mistaken Pat, Rick and Beth as Dragon King and his minions. Justin attacked them until he was helped by them for a cup of tea. Justin then told them about his past and told them about him not knowing how to fix his current situation. Pat then promised to help him and let him sleep in his house. Later that day, Courtney tried to use the Cosmic Staff after it refusing to be used by Courtney who did not trust herself at the time. Justin saw the shimmer of the staff and walked in saying "our queen has risen.".
