In the new NBC drama, the computer whiz assists former cop Faraday in his crusade against crime as superhero The Cape.
Glau told the Los Angeles Times: "I know from my perspective [and] the way that I'm playing Orwell how I feel about Vince and what I'm trying to portray throughout the episodes that we've already shot. I'm really interested to see what people think and if they're picking up on what I'm trying to express."
She added that Orwell has a "cool dynamic" with her partner, who is desperate to return to his wife and son.
"Her relationship with Vince is like a real-life relationship," she said. "Her feelings, what she would like to have [and] what she wants him to think about her is very complicated."
Glau's co-star David Lyons previously dismissed the suggestion that a romance could develop between Vince and Orwell.
The Cape airs on Mondays at 9/8c on NBC.
