As a federal investigator with no personal reason to give Oliver the benefit of the doubt, Samanda could pose a great threat to Oliver’s operation as the Green Arrow in the new season.
While Samanda won’t be the first character to attempt to figure out everything there is to know about the Green Arrow, she will be one of the few who has actively tried to figure out how Oliver is connected to him.
Journalist Susan Williams in Season 5 figured out a great deal about Oliver as well, although she ultimately decided not to report any of his big secrets.
The cops back in Season 3 had to be told be told that Oliver was the Arrow, and they stopped investigating him once Roy took the fall (and faked his death) for him.
