Barry takes advice from Iris and Cisco to defeat Cold in a whole new way - by being a better thief. Donning a new persona and costume, Barry becomes Silhouette, the best thief in Central, who consistently beats Captain Cold to his heists, stealing the loot out from under him (while secretly having made a deal with the proprietors, and returning the loot later). Cold isn't sure if he's upset by this new player targeting him...or intrigued. Eventually, the truth comes out.
