Two questions

While watching the second season, I noticed these guys appearing as "background aliens" in several episodes, including The Way We Weren't and the "Look at the Princess" trilogy. Should I add these episodes to the Appearances section, or is that only supposed to include significant/plot-relevant appearances? Different wikis I've seen have gone different ways on this.

Also, where does most of the information here actually come from? It's not sourced and I don't remember it being mentioned in the show. 04:49, September 16, 2013 (UTC)
