Hit the engine room after Aya and you’ll chat with Gil, where the subject of his gambling "hobby" will come up. He’ll challenge you to a game next time you’re at port, so make your way to the Nexus (perhaps in pursuit of the video archives Liam wants for "Movie Night: Getting Started"?). When you return to the Tempest, you’ll discover you have an e-mail from Gil. Read it, then head to the Docking Bay on the Nexus to find Gil waiting for you… like a wolf waiting for a sheep. Play him and SAM will suggest that he can be your wingman and provide you an edge. If you use SAM, you’ll win, if you don’t, you’ll lose. It doesn’t matter much either way, the only point of this quest is to build up your relationship with Gil, for what that’s worth.
