Mathew Gurney is the father of Aaron and Nate Gurney.
Matthew is homophobic, and is extremely upset when he discovers his son Nate is gay.
His son Aaron was a soldier, and was killed in Afghanistan. Tom Clarkson offered to set up a foundation in Aaron's name, but Matthew reacted to this by beating Tom to a pulp in the pub, leaving Tom with PTSD from the incident. After the attack, Matthew walked out of the pub and is not seen again.
