In my current WIP, my two main characters have been together most of the time until the chapter I'm currently writing. In the times that they've been apart from each other previously, I only had to deal with one or the other, so I didn't have to worry about going back and forth. In the current chapter, however, they're going to be separated for most of it, and I'll need to go back and forth. Would I be better off using a line or something like that on the page to show when I'm going from one character to the other, or just let the story itself tell the reader that? If I didn't make myself clear enough, by all means tell me. I'm not really sure how to ask that question so that it makes sense.
