"He had on similar green clothes and heavy shoes. Their shirts differed, one had stripes on his sleeves the other’s plain." These are two strangers my first person narrator will be talking about in the next few pages. She doesn't know their names. I need the reader to know who is talking when she relates their dialogue so they need temporary nicknames. I'm using Plainshirt and Stripes. After a couple of references to "the man with..." comes the following: "“Look what she’s wearing,” Plainshirt with the metallic box to my side said. Stripes reached toward me and I reflexively shrank back." My question is, does my narrator need to say "I gave them nicknames"? Would the above wording where the nicknames are introduced without saying anything be clear without pointing it out? And do the names need single quotes when first introduced and/or every time they are used? "“Look what she’s wearing,” 'Plainshirt' with the metallic box to my side said. 'Stripes' reached toward me and I reflexively shrank back." Thanks.
