User blog comment:Mineko Charat Lucky/League and the Institute has nothing to do with League of Legends anymore(?)/@comment-7782121-20130815070803/@comment-4814368-20130815211039

Maybe we could justify it by saying Lucian wants to learn more about Thresh's fighting capabilities, etc. before actually facing him outside the League. It's a stretch, but it would make sense for them being on the same team now and again too.
