"Unmasked" is the eighth episode of the seventh season of Arrow, and the one-hundred-forty-sixth episode overall. It aired on December 3, 2018.
Felicity stands by her recent decisions regarding her family. Meanwhile, Diggle and Lyla continue to look into the Dante painting that Curtis found.
The title references Oliver fighting crime for the first time since his release where he does not wear his hood and mask, plus Diggle and Lyla's investigation into the Dante painting that revealed the names of the Longbow Hunters, and the reveal of the Unidentified Green Arrow's identity.
Sea Shimooka is credited in the main cast bill starting with this episode onwards.
Two old locations from past seasons of Arrow makes a return:
According to Oliver and Felicity, the beginning of the episode takes place during their anniversary. Interestingly, this episode aired almost exactly 1 year after the DC's Legends of Tomorrow episode "Crisis on Earth-X, Part 4", which is the episode in which they got married.
At the very beginning of the episode, Felicity says that she really misses William and Oliver replies that Christmas vacation seems like it's "20 years away". This is possibly an inside reference to the fact that the flashforwards take place roughly 20 years in the future and William is a major character in them.
