Oliver finds a man who passes by the name "The Mayor" is getting illicit firearms to The Glades, so Oliver supports a "Money for Guns" occasion to help tidy up the city. Lamentably, The Mayor crashes the occasion with his group and truly harms Sin. The Canary is irate when she learns her companion is in the medical clinic and sets out for retribution. In the interim, Felicity staggers Oliver with a touch of data about the Canary, Donner asks Laurel to supper, and Diggle reconnects with an old companion.
