On a writing note, it was a little difficult to keep track of your post because it meandered so much. You also need to keep the verbosity to a minimum with some ruthless editing. Your post had the feel of someone who spills all his undirected thoughts onto the page because he isn’t sure what he wants to say. That’s fine when you’re brainstorming, but once you have your ideas written down, you need to iteratively condense and reorganize them, piecing the ideas together in such a way that the transitions are natural and each piece supports the overarching structure.

For example, at the end of your first major paragraph, which is where you should lay out the structure of your post, you raise the question of whether we need to reinterpret the events at the end of SoD. Then you muddle around for two paragraphs with one sentence devoted to what actually happened at the end of SoD. Then you explicitly break away to discuss something else entirely. Two paragraphs later you come back to the topic, reaching a tentative conclusion that vaguely agrees with your earlier comments, but doesn’t actually account for them. In the entire post, you never attempted to present the standard interpretation of the end of SoD, let alone a reinterpretation. You have a lot of material to work with on this point, but you never organized it into a coherent analysis. Something along the lines of…
-Brief summary of end of SoD
-Standard conclusion about Redcloak drawn from end of SoD
-What about the events in the latest comic(s) casts doubt on that conclusion
-What alternative conclusion those events support
-How well that conclusion fits into the rest of the narrative

…would have communicated a lot more to the reader, and provided a reasonable grounding to talk about Redcloak’s tragic devotion to the Dark One, or to speculate about how Redcloak intends to handle Xykon after recent events. Without that grounding, the rest of your post felt sort of pie-in-the-sky.

Also, run-on sentences lead to rambling, undirected writing–after all, they’re the product of rambling, undirected thinking. It’s a symptom rather than the problem, but disciplining yourself to write separate concise sentences that work together will help you to put your separate thoughts together in a way that flows.

Hope that helps.
