There are some episodes of Arrow that do not need to exist. Before the brief hiatus, we witnessed the break-up of Oliver Queen and Felicity Smoak. While the break-up was also coupled with Felicity regaining the ability to walk, it was a slightly stunning development. Tonight's episode drives the finality of their break-up by bringing back one of the lamest villains in series history, Cupid. While Cupid's initial appearances capitalized on the thematic link to Valentine's Day, her appearance tonight feels a bit forced and out of place. It also doesn't help that the series continues to employ the lame backstory narrative device.
