Daniel was introduced in season 2 as an artist who immediately showed an interest in April Malloy. She wants to keep things fun, but eventually decides to introduce Lucy to Daniel. After Lucy and April both realize they love him (as a dad and a partner, respectively) and April began to track his mysterious behavior, Daniel reveals that he is married. April, filled with guilt, continues her relationship without telling anybody. Eventually, she stops the relationship. A few months later, she sees him in an FBI jacket when the FBI are investigating Paul, April's supposed ex-husband. There, she discovered Daniel was an undercover agent who was assigned to contact Paul through April from the very beginning. When April and Lucy's lives are threatened and Daniel takes them to a safehouse before Joss' wedding, Daniel and April have sex. At Joss' wedding, April re-mourns her husband and mentions that she can see a new future with Daniel.
