Katherine (Chris's sister) and Deniz bonded on the Rivera family vacation to South Africa in September 2017. When we got home, she set us up on a friend date given that Chris had just moved to London and "had no friends." After knowing eachother for 23 days, Chris booked a ticket to Australia to join (crash?) Deniz's winter holiday. It obviously went well and Deniz cancelled her move back to New York. The rest is history.
