That isn't OOC banter, that's just my narration style - it's quite detached and self-critical. "Meta" i believe is the word. Of course, that's not for everyone so I do try to keep it down as much as I can if people request it as you did earlier, but in the end it is still my narration style and it'd just be impossible for me to cut it out completely. I find it hard to engage with writing that's just one long block of "character did this" etc, so I ended up naturally evolving this meta-ness. Personally, I like it - it makes the writing feel like it's self-aware; like it knows it's just the ramblings of a slightly deranged teenager.
