Powerful acting by Danny Miller (Aaron) ... he finally reveals, in the pub, what is eating him up. He did try so hard to make Jackson see that his life was worth living, and it wasn't fair that Jackson couldn't see it, and so he feels like a failure. He deserved to win the Best Actor Awards for both 2011 and 2012.
His name is Fynn, Aaron dated him a few times after Jackson broke up with him, but Aaron couldn't get over Jackson so he ended it with Fynn and get back together with Jackson.
