Harry is hard at work in Earth 1's STAR Labs. During this hour we will learn more about his life on Earth 2, before coming through the breech. Here's hoping we learn a lot more about him being a father! That's such a cool surprise.
The plus side of Harry Wells walking, is he gets to take his badass self out into the field and get his hands dirty. I like it and really hope he doesn't go bad this time around. Being a dick? That's OK.
One mystery I cannot figure out is why some people come into our lives and why some people go. Others become a part of you. Some friendships feel like they'll last forever and others end far too soon. Not every friendship is meant to last forever. What does last forever is the pain when that person is gone.
