Kate McReary is a potential love interest of Grand Theft Auto IV protagonist Niko Bellic. She is the sister of Patrick, Francis, Gerald and Derrick McReary, and the daughter of Maureen and Mr. McReary. She's traditional, and according to Patrick "she won't put out". Despite this, you are still given the option to try and join Kate inside. Depending on the players choice of ending, Kate can die. If the player chooses "Deal", Kate goes on to live, whereas if you choose "Revenge", she meets her end at the hands of Jimmy Pegorino at Roman's wedding.
If the "Deal" option is chosen, Kate berates Niko for doing the Deal. After Niko kills Dimitri, Kate calls him, telling him that she heard of his cousin's death, and will be there for him.
