Thanks for your edits on the wiki, you do good work and it's much appreciated.
You'll notice that there are articles named 2x08, 2x09 up to 2x15. They are "placeholders", the first one is for Season 2, episode 8, and so no. I create these before we know the names of the episodes so that we can put any info we get about these new episodes somewhere.
When we learn the names of new episodes, rather than create a new article, just rename the existing placeholder article and this saves any info on the episode that was already there. So this morning for instance, I renamed 2x07 to Shiva. (I made sure to have a look in your new article for any new info before it got copied over.)
Please don't stop what you're doing, I guess you're in the US (or somewhere) and you get info sooner than I do about new ep names, so just rename the placeholder article for that ep to the new name when you find out what it is.
Hope you're enjoying Season 2, it's certainly very different to The Walking Dead and I think it's a step up from Season 1 as well.
