The Glasgow Warriors flanker was among several Scotland players who produced standout displays as Gregor Townsend's side responded emphatically to the frustration of their loss to Italy, bringing England's 12-match winning streak to an end.
That result has reignited Scotland's Six Nations hopes, but Darge knows they will need to reproduce the same intensity and standards shown at Murrayfield when they run out at the Principality Stadium on Saturday.
"I guess it's looking at what worked for us, how we got into this sort of place mentally and emotionally, doing what we can to replicate that performance," Darge said.
"We'll do the same process that you normally do, review this game. It was absolutely brilliant, but there will be bits of the game that we can work on.
"It's important to look at that, regardless of win or loss, because you ultimately want to keep growing as a team.
"A point we spoke about earlier in the week is, off the back of Italy, we can do all the talking and meetings that we want, but it is about actions. I think it was the actions [against England] that were really pleasing. We just want to carry that on."
