I don't think Hank is as skittish as I've thought him and unless his mutation is pointed out, he seems pretty confident. He is still "square" though, and I think he craves the approve of authority too much.
I don't think he was as cowardly in Shaw's attack as I first thought. A lot of my first perception of his cowardice was from stills or gifs on Tumblr where he is behind everyone. These were out of context. From watching the movie, I can see all those shots were when the group was changing direction. Hank lead as often as he followed. He also suffers from being the tallest person and thus being pushed to the rear of shots so the other actors could be seen.
I still think he was mean to Raven but it was a blind or thoughtless mean, not a malicious mean. He honestly wasn't ready to let go of the dream of being normal and thought she was with him in this regard. To find out she wasn't was a shock. I think she also made him doubt his dream which upset him. Still doesn't make what he said right but it's more understandable. I also think he still was doubting his dream when he took the formula as you could see him struggling with his decision up until he inserts the syringe.
I still don't see the Alex and Hank ship that seems so popular. Alex was mostly an ass to Hank and did a lot of verbal bullying. Alex and Darwin I can see but not Alex and Hank. I guess i just have a problem with bullies and their victims falling in love.
