Even though Earth-1s Harrison Wells was one messed up cat, he had some truly great moments with Barry Allen. Not only a mentor, Wells was like a father figure to Barry. And in Fast Lane, we saw another look at this dynamic one more, even if this time it involved Earth-2s Harrison Wells. In fact, even Barry himself says how its just like old times as he sits under the learning tree of Wells. It really was great to see until Harry ruined the moment. Snapping at Barry and declaring how he didnt ask to be a mentor, how he already has his own kid, Wells loses it and tells Barry to beat it. Again, not cool, Harry. Not cool.
