Three years of frustration had come to a head.
"Just a little shoutout," Kaepernick said.
"I think you know the answer," Kaepernick said with a grin.
Kaepernick said he "will never forget" that he was selected in the second round of the 2011 NFL draft, 35 spots behind Newton, the Heisman Trophy winner and the top pick that season.
Kaepernick completed 15 of 28 passes for 196 yards in the divisional playoff win, avenging his worst statistical performance of the season two months ago against the Panthers.
"That's not the first, nor will it be the last time somebody does that," Newton said of Kaepernick's copycat display before leaving the postgame podium.
"I think we're the two teams that everybody was looking at from the beginning," Kaepernick said. "It's going to be a knockdown, drag-out game."
The Seahawks' 29-3 win over the 49ers from Week 2 will air on Tuesday, Jan. 14 at 3 p.m. ET. and at 10:30 p.m. ET.
The 49ers' 19-17 win over the Seahawks from Week 14 will air on Tuesday, Jan. 14 at 4:30 p.m. ET. and Wednesday, Jan. 15 at 12 a.m. ET.
San Francisco (14-4) split two games with the Seahawks this season, but lost 29-3 at CenturyLink Field in September.
"That's the great thing about our team - we have weapons all around," Boldin said. "You try to take one guy out and you still have two or three guys left who can make big plays."
It was a rough playoff debut for Newton.
"Terrible ending to a great season," Newton said.
Almost fittingly, he misfired into the end zone on the final play of the game.
Kaepernick was held to 91 yards passing, 16 yards rushing and sacked six times in the first meeting with Carolina, a 10-9 loss at Candlestick Park.
But he played efficient football Sunday.
"We had to get settled down," Kaepernick said. "We came out, they did some unorthodox things against us. We settled down, we got into our rhythm, we started making plays."
San Francisco led 13-10 at the half when Kaepernick scored midway through in the third quarter on a 4-yard touchdown run off a read option.
All turned out fine for the 49ers though, as officials overturned the call ruling Davis dragged his left foot and scored.
Television replays showed the 49ers had 12 men in the huddle with backup tight end Vance McDonald racing to the sidelines before the ball was snapped. Referee Carl Cheffers defended the call telling a pool reporter the ball hadn't been spotted - although Fox television replays seem to indicate otherwise.
