Excitement, nerves and a great-big smile - all three, visibly present when he took his first turns on that iconic canvas at LA Live. And certainly, as we inch closer to puck drop, the butterflies and business side will clash with one another, too.
But how can you not savour the moments like these; the memories, that for a legion of Kings fans, have left a lasting impression?
So, for now, he'll soak it up.
"My dad will be here," Lewis said. "My wife and kids were going to come down, but it's too hard with the kids and flying and all that. I think my dad circled this one right away and we made sure he was going to be here."
Lewis has been a valuable addition to this Flames this team this year. On Wednesday, Head Coach Darryl Sutter paid him the ultimate compliment by saying his game hasn't changed one bit in the past 10 years - that his hockey IQ and superb, at-speed processing power allows him to "manage" games more effectively than most.
He's also at the forefront of the Flames' revitalized culture.
He sets the bar when it comes to work ethic and constantly picks at his craft.
He, along with Milan Lucic and fellow Cup champ Brad Richardson, have given Sutter and the Flames everything they could ask for from a fourth line.
They're trusted to play big minutes and are often the go-to guys late in games to help close it out.
"For us, everyone plays and everyone has a big role in it," said Richardson, who was part of the 2012 squad, but has been back to L.A. before as a member of the Canucks, Coyotes and Predators.
"On some teams, the third or fourth lines don't play very much and the fourth line doesn't play at all on some teams.
"We use every line. We need every line to be good, and I think that has a big buy in on the team that everyone feels important.
"And that's the way Darryl's teams are."
