Kate McReary

Kate McReary (born 1980, age 28) 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 and youngest child 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.

According to Patrick, Kate witnessed several bloody fights between her brothers; seeing Gerry beating Francis was a traumatic childhood experience for her. Over time she has apparently become accustomed to living close to violent crime, falling for Niko despite disapproving of his lifestyle.

Fate
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.

Glitch
If the "Revenge" option is chosen, Kate dies at Roman's wedding, however she may still call Niko from time to time as Unknown Caller to make a date. As her contact is deleted from the phonebook, she cannot be called back.
