Hey, Blacklist Wikiers. I'm just a visitor, but have a suggestion. I came to the Wiki to find some information for my parents, who are new watchers of the show. They were having a hard time remembering if "Berlin" was dead or alive and wanted me to look it up for them. I came here, knowing only a little about the show, to find an answer to this, armed with the character's name (Berlin) and the episode they're on (early in season 2). Should've been easy, but... your characters listing didn't have any "Berlin" listed. I asked my parents if the guy had another name, which they insisted they didn't know of any.
I eventually found him under Milos Kirchoff, his real name, but saw that at the point my parents are at, that information hadn't been revealed yet (so not their fault for not knowing it). Your wiki would be easier to navigate for casual users and/or people new to the show if you had some categorized redirect pages for character aliases. Just a suggestion!
Other than that, you guys have a nice wiki here :)
