Judging by a recent TVLine spoiler report, Donna Smoak (Charlotte Ross) is going to have a more substantial role to play in season 4 of Arrow.

Both Stephen Amell, who plays Oliver Queen, and Paul Blackthorne, who plays Quentin Lance, dished about certain aspects of Donna's character arc in The CW series.

For one, Oliver is really going to hit it off with his future mother-in-law. "I had always imagined that Oliver in his nice, easy-going state would have a dialogue with Donna Smoak, which was proven correct and leads to some funny moments," he said. "The dynamic between the two of them is excellent."

But what is way more interesting is the possibility of Quentin and Donna meeting each other, and sparks flying.

Blackthorne has definitely dropped a huge hint in that regard as he teased a possible love interest in upcoming episodes, which could very well be Donna.

"Do I have lipstick on my cheek? [Then again] it's a Christmas episode, so of course, everybody's kissing everybody," he said.

The next episode of season 4 of Arrow, titled 'Haunted,' will air on Nov. 4 on The CW.
