Charles Venn firmly said that his appearance at Blackpool was "cathartic" after everything he had been through on the show.
His actor and professional partner Karen Clifton has had a rocky time in BBC competition, ending three dance-offs.
But on Saturday they got two 9 and two 10, giving them the highest scores so far.
Speaking at the spin-off event It Needs Two, Venn said: "Still not fully immersed, what happened on Saturday.
"I'm still in shock, honest. That was the last thing we expected. "
Venn said the show was "not tainted" because he and Clifton celebrated how far they had come and arrived at Blackpool Week.
He said: "Actually we always work hard, but it's only electricity in the ballroom and knowing its history – it only gives extra excitement in our steps.
"It was a catharsis performance on the dance floor because of everything we went through until then, it was a celebration, and we would appear in style, if that was needed."
Clifton added: "We have gone through so many lows. We have been beaten – three dance matches, 25 clubs …
"And we are just, like, you know what, we have nothing to lose, we just want to enjoy ourselves.
"We really have parties out there."
