According to ET Online, Parker Young (Suburgatory, Enlisted) has joined season 4 of Arrow as a character created just for the show named Alex Davis, who's described as "a smart and driven young man, who will work for Oliver Queen (Stephen Amell) and become a potential love interest for Thea (Willa Holland)." This will be a "meaty" recurring role.
With Roy Harper (Colton Haynes) out of the picture for the foreseeable future, it seems the young Queen girl is going to be taking some steps towards moving on and finding a new fella. Will that be Alex? Unless he also happens to be a superhero he's going to have quite a bit to live up to.
Arrow season 4 premieres Oct. 7 at 8 p.m. ET/PT on The CW.
