During the Anti-Monitor Crisis, Pete as well as everyone in the multiverse except for the seven Paragons, was killed in an antimatter wave by the Anti-Monitor on December 10, 2019, only to be restored a month later, after the Paragons and the Spectre created a new universe.
Pete, a linguist, spends much of his time reading and became a fan of Kara Danvers, suspecting from her work in CatCo Worldwide Media that she must have a deeper understanding of English than an average person who only knows one primary language.
Kelly called him when her friends needed some help. At the United States Congressional Library, where he works, he met Alex and Kara, whose origin he questioned, but she assured him that she was raised in Midvale; they asked him to help in researching Leviathan. However, Alex and Andrews were hunted down by an unknown assassin due to their efforts. Pete, after calling his wife and learning that their house was being watched, went into hiding because of this.
