Duncan Keith spent a few extra seconds with Jeff Carter in the handshake line Saturday night, no doubt apologizing again for the high stick in Game 3.
Keith was suspended for Game 4 for the incident.
"The whole suspension thing, obviously, I've said enough about it," Keith said. "It wasn't what I meant to do, even though it didn't look very good. You know, I talked to Jeff a little bit. I know him from the Team Canada camps, playing against him a little bit. He's obviously a great player. It was good to see him come back when he did.
"I've got a lot of respect for a guy like that, for him, the way he plays, how hard he is to play against."
Keith returned with a bang, scoring at 3:42 of the first period on a slap shot that found its way through Kings goalie Jonathan Quick.
"It was nice to see that one go in," Keith said. "I didn't really expect it to. I was just trying to get it on net.
"Against a team like L.A., we always want to score first. I think going forward it's going to be similar playing a team like Boston."
Keith played 40:12 in the victory.
"I thought he had an outstanding start to the game," Blackhawks coach Joel Quenneville said. "Logged 40 minutes and was out there with a great gap."
Patrick Kane is just the third player in NHL history to score 3 goals, including an overtime tally, in a series-clinching win.
The others were St. Louis' Jorgen Pettersson in Game 4 of the 1984 Norris Division semifinals against Detroit, and Edmonton's Esa Tikkanen in Game 7 of the 1991 Smythe Division semifinals against Calgary.
The last player to record a hat trick in a game in which his team clinched a Stanley Cup Final berth was Los Angeles' Wayne Gretzky, who did so in Game 7 of the 1993 Western Conference final against Toronto.
Kane's other postseason hat trick came on May 11, 2009, in Game 6 of the Western Conference semifinals against Vancouver. He has 2 career game-winning goals in 68 playoff games, the first of which came in overtime of Game 6 of the 2010 Final against Philadelphia.
Kane's third goal was the winner at 11:40 of the second overtime and came on a 2-on-1 with Jonathan Toews.
"You know, the shift before, actually Johnny had the same play and the puck fumbled on him," Kane said. "I knew he was coming back to me. I just tried to wait for the defenseman to go by me and tried to get it off as quick as I could in the net."
Get it together:
The Hawks had to take a deep breath and regroup after Mike Richards tied the game with 9.4 seconds to play Saturday.
"I honestly don't think there's a worse feeling in hockey, when your nine seconds away," Joanthan Toews said. "You know you have to get the puck out. Two little bounces go against you, next thing you know it's in your net. Your heart sinks pretty quick.
"We just tried to tell each other in the locker room that we can't be thinking about what could have been, we have to just turn the page, get over it. It's the only way you're going to move on and win the game."
•Bryan Bickell recorded at least 1 point in all five games of the Western Conference final, totaling 3 goals and 4 assists. Bickell has 8 goals and 13 points in 17 games this postseason, all career highs.
•Each of the 14 series contested thus far in the 2013 Stanley Cup playoffs has had at least one overtime game. That had never happened since all four rounds went to the best-of-seven format in 1987.
•The Hawks improved to 9-1 at home this postseason, are 6-1 in 1-goal games and 3-1 in overtime.
•The Hawks and Bruins have faced off six previous times in the Stanley Cup playoffs, but never in a Final. Their most recent meeting was 35 years ago, when Boston swept Chicago in the 1978 quarterfinals.
