Heh, I read a lot too, but I lack imagination. I find fanfics hard to read as well, probably for similar reasons but that would be a long topic to break down.
Grammar was just small things, mainly capitalisation. I have a habit of often forgetting to do it myself after spending a lot of time typing online. I forget which script, but there was a long run-on sentence; it's possible you made a mistake punctuating and it just looked that way. As for spelling, I don't really recall for sure, but "luscious" looked odd. I had a few beer in me when that script came up though, so it might have been me. Sometimes words look odd to me even if spelled correctly. both scripts have only come up once for me so I haven't had a chance to be more specific, sorry.
Very minor things, and honestly they don't bother me. I wasn't sure if I should even mention them in the first place, which is why I didn't elaborate.
