Iris' significance in the series starts when Brother Justin informs her about the church board's plan to take away his new ministry. Shortly after, a fire in the church kills several orphans, but it remains unknown until the end of the first season that Iris was the arsonist. Radio show host Tommy Dolan, who arrived to help with the arson investigation, develops feelings for Iris, but a romance is hindered by Brother Justin's return from a week-long self-discovery trip.
