Jenny was involved in relationships with two fellow employees, Alan Dalton and Dobson O'Gill. In her terminal entries, she makes an excuse to avoid hanging out with Alan, subsequently inviting Dobson over instead. Unbeknownst to her, Alan and Dobson were also romantically involved, with Alan mentioning to Dobson that Jenny was busy, also inviting Dobson over.
Jenny also corresponds with the two of them on business-related topics, mentioning to Alan that she does not know why RobCo Industries is coming after H&H Tools so aggressively or if there is something personal between the two CEOs. She told Alan that she tried to check RobCo's SEC filing information with no luck. She says she will email Dobson, who has a brother that is a private investigator with corporate experience.
Jenny DeSoto is mentioned only in Fallout: New Vegas.
