I initially read your fic as omniscient POV, as I was reading Cam as someone who knew exactly what was going on between the two characters in the fic. But I see now how it is actually limited POV.

And yes, I have used proper omniscient POV before, but no I don't usually like it. I think the problem with the fics I wrote was that they involved a Mary Sue. Plus, I think it sometimes creates too much distance, especially if it isn't written through the eyes of a character but simply the fanfic writer themselves.
Actually, here's a question: can it be omniscient POV if it's through the eyes of a character? Or does that instantly make it limited?

The "this" was omniscient, simply because of the fanfic feel the show has. Of course any historical show could probably get away with omniscient pov fanfic.

You're not dense, I'm just not reading things properly.
