Arrow Season 4: 12 Big Questions After 'Beacon Of Hope'
8. Is Curtis Going To Become A Permanent Member Of Team Arrow?
A big part of why this episode was so much fun was the presence of Curtis, who as Diggle remarks serves as "a taller, more dude-like version of Felicity.”
Yes, Curtis brings a comedic tone into the Arrowcave (a much better name than 'the Bunker'), from his bumbling over learning Oliver's secrets to his joy and disbelief at working with Team Arrow, and the more physical comedy when he's destroying the cave running away from a bee.
Although his personality is very different to Oliver's he makes for a good fit for Team Arrow, because he is essentially like Felicity in Season 1, and if she's staying away then he is certainly a capable stand-in, and it wouldn't be a surprise to see him join the team in this role more often going forwards.
