He said Karlsson was a big help to his development, especially last season, his first full one with the Senators.
Now here he was, playing against the man who had taught him so much. True to form, Karlsson gave the kid another lesson on this day, swooping over to knock the puck away just as Chabot thought he had an open lane into the Sharks zone early in the game.
The two exchanged light-hearted barbs about the play in the hallway between the two dressing rooms during the first intermission.
"We were just having some fun," Chabot said. "I mean, of course it was different seeing him in a different jersey, but we saw it as another game. He's not the first player coming back after a trade or something else. But it was a great game and we were happy the way we played and we're happy to get the win."
Karlsson was similarly enthused about being able to play in front of the Ottawa fans again. But the loss -- the Sharks' fourth in a row (0-3-1) -- left a bitter taste in his mouth.
"I was happy to be back but it wasn't a good game for us," Karlsson said. "We're struggling right now. You are going to go through periods like this. We're a better team than we've shown in the past four or five games here. We know that. At the end of the day it's up to us in the room to figure that out."
Karlsson spent Friday chatting with his close friend, ex-Senators forward Daniel Alfredsson, who had gone through a similar experience of returning to Ottawa with another team exactly five years earlier.
Alfredsson, a mentor to Karlsson with the Senators from 2009-13, left Ottawa as a free agent to sign with the Detroit Red Wings in 2013. Alfredsson scored a goal and had one assist in his return to Ottawa on Dec. 1, 2013. The 4-2 Detroit win was a mere sidebar to the love shown to Alfredsson by the crowd of 20,011, which chanted "Alfie, Alfie!" during a pregame video ceremony honoring his 17 seasons with the Senators.
"I remember Erik and I drove to the rink together that day," Alfredsson said. "Now here he is going through what I did.
"He was fine. He knew it would be emotional and awkward. It's like telling somebody that's expecting a kid, you can't explain it until you go through it. It's the same thing here. We're all different. You can't prepare for it, that's impossible. My only advice: I just told him to enjoy it and take in the moment."
He did exactly that. So did the fans.
