Just thinking of it now... but you know, I'd like to see fic with Six and one of Peri's friend's from America. Or one of Peri's descendants after he goes up to check on her and arrives a bit too late.

Or, just fic with him checking up on her.

There was something, and now I can't remember if it was fic or Big Finish because it's all getting flustered in my head, but there was a thing where Six and Erimem brought Peri a cat which was very sweet.
