Vaughan made his long-awaited return from injury in the 1-1 home draw with Charlton Athletic – as a 64th-minute replacement for Wells, who had put his side, reduced to 10 men by the disputed dismissal of Murray Wallace, ahead in the 50th minute.
Town were pegged back by Igor Vetokele’s reply in stoppage time, and remain 20th in the Championship.
But Bermudian ace Wells, who now has four goals for the season, was quick to take the positives.
“We gave our fans something to get excited about, and if a late penalty appeal (involving Vaughan) had gone our way, we would certainly have won,” said the 24-year-old.
“To have played with 10 men for half the game and still got a point is encouraging.
“The timing of the red card (in first-half stoppage time) was especially tough, but we defended well and broke forward whenever we could.
“It looked like we’d win but it wasn’t to be.”
Vaughan, 26, had been sidelined since March because of knee, then calf injuries.
“It was great to see him back,” added Wells.
“With only 10 men, we couldn’t have had two strikers on the pitch.
“But I reckon we’ll be playing alongside each other soon, and I’m looking forward to that moment.”
