"Winning tonight doesn't really mean anything in the end.
"I'm here to do a job with this club and beating your old team is neither here nor there.
"I don't really have any inner satisfaction, more than I would for a normal win. I'm obviously satisfied but it didn't motivate me."
In a largely physical match, Keary copped surprisingly little chat from the Rabbitohs players.
The 25-year-old joked after the match that Souths players must have been told to ignore him.
Perhaps the same edict was followed by their fans.
While those at ANZ Stadium offered a small jeer with his first touch of the ball, just 10,479 fans turned up for the match - the lowest for the derby since 1998.
But those who stayed at home missed a lesson in attacking football early from Keary and halves partner Mitchell Pearce.
They combined directly in the lead up to two of the Roosters' three tries, as the free-flowing football which sees them playing both side of the park continued.
"That's the way footy is meant to be played," Keary said.
"I just think it's a bit of a blight that halves don't get to play with each other in different structures.
"Someone is meant to be there running a team and he's got to have his kind of men around him that help him out a bit."
