But when Karen Elaine Harrelson, 48, and Gregory Stambaugh, 57, were preparing for the finale -- drinks in hand -- they stopped agreeing, Fox 40 reported.
The pair got into an argument over which contestant should win this series. One picked winner Candice Glover, and the other picked runner-up Kree Harrison.
During the argument, one of them picked up a kitchen knife and stabbed the other, according to the York Dispatch.
West Manchester Township Police said that then, whichever one was stabbed first took the knife and stabbed the other with it.
The two bickered over who started it and did not give police a consistent story.
Harrelson and Stambaugh were treated at a local hospital for non-life-threatening injuries, then transported to the police station. They each were charged with two counts of simple assault and one count of aggravated assault.
They are being held in the same prison in York County, Penn. Harrelson is there on $30,000 bail and Stambaugh on $70,000.
Police retrieved two knives and two bottles of alcohol from the home.
