Question about writing in the third person limited. At the end of the paragraph, I have a single sentence that I wrote in three different ways. I want to know if any of them are simply wrong for writing in third person limited or if they carry different meanings at all. Personally, I don't like using italics to write character thoughts, but sometimes in writing, I don't add 'they thought' to the end, like in the first example. Anyone willing to share their thoughts on how this should read?
