The members of Team Arrow have to constantly be working at maximum efficiency, which doesn’t leave a lot of wiggle room when it comes to having parents visit on the CW's "Arrow." Luckily, fans know the character Felicity Smoak (Emily Bett Rickards) well enough to know that she can handle anything, including an extended visit from her mother.

It was previously revealed that Felicity’s mother, Donna Smoak (Charlotte Ross), would return to Starling City (now Star City, but who’s keeping track?). Fans knew to expect the ditzy Donna to return as early as Season 4, episode 6 – but that plan has changed a bit. According to TV Line, Donna won’t just be guest starring in another one-off episode, she’ll have more of a character arc in the series as the actress has signed on for an additional two episodes, bringing her total appearances in Season 4 to three.

Ross, whose previous credits include shows “Hit the Floor,” “Nashville,” “Glee,” “NYPD Blue” and “Days of Our Lives,” told the outlet that she’s been surprised what a different experience it’s been like working on the hit CW series.

“I’ve been in this business for a while and I’ve never seen anything like it...I’m just so overwhelmed with gratitude.”

Donna Smoak last appeared in the Season 3 episode of “Arrow” titled “Public Enemy.” When things seem at their darkest for Oliver Queen (Stephen Amell) and Felicity, Donna takes the screen to inject a little comic relief and motherly advice. As IGN notes in its recap of the episode, she isn’t a strong character like, say, her daughter. However, that didn’t stop her from taking an objective look at Felicity’s life and realizing that she has a choice to make between a relationship with Ray (Brandon Routh) or her unyielding feelings for Oliver. In truth, it’s really all Donna’s doing that Felicity [SPOILER ALERT] finally ends up with Oliver in the end of the season.
