Kate McReary
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 loses all respect for Niko, and will no longer speak to him until after the final mission. In that storyline, Roman dies at his wedding instead.
