I have it on good authority that the incident was the culmination of an argument between Link and Kurtley. It turns out their relationship was more than just coach and player but with the recent announcement of JOC (James O'Connor)'s return, Kurtley wanted to try and reignite the old flame. This upset Link, and Ms Patston, who is actually also Link's illegitimate daughter, tried to defend her father. Upon finding this out, members of the Sydney University Rugby Club, in an attempt to lure Kurtley to play for them, deleted all record of Ms Patston's education and tipped off the media.
Meanwhile, the reason why she had to head home, was because she found out Will Skelton was coming on tour and was concerned about seeing him as the last time they were together their passionate affair had come to an abrupt and ugly end.
Sources will be withheld to protect their identity, but let's just say they would make a great long haired inside centre.
