It all started when Kaitlin went to Claire's college graduation celebration and Heidi's 50th birthday party at the Ode farm. Paul and Kaitlin had been introduced for the first time along with all the other siblings. Then a few weeks later both Kaitlin and Paul had seen each other again for Claire's 21st birthday, that's when it all started! About a month after that Paul had worked up the nerves to ask Kaitlin out on a date and she turned the invite into a double date with Christian and Claire.
