I have little experience GMing Fate. In fact, my only experience so far is a "twosie"/one-on-one one-shot with my best friend, Z. I've been researching an enormous amount of materials, as well as reading both manuals, and after a gargantual overcomplication failure with D&D I'm very afraid of failing with Fate as well.
Z has been around for most of my research and is quite well-acquainted with the rules of the game, as well as the fundamental conceptual differences between D&D and lighter systems. She's going to have her character readily-made, whereas the others will make them during the first session.
Neither of us are in any way experts, but I've documented myself and prepared a lot, and Z has a feel for the game and a willingness to help me that I feel will help me quite a bit. So how can I have her, as something of a "GM lieutenant", help me get the other players invested and acquainted to the game better? What are a few concrete ways that she can be a bridge between me and the others?
