He was first 'judged' as terrible for checking his phone. Then we find out that he was removed from the scene and was likely glued to his phone for an absolutely 100% valid reason, and you still want to judge him for being a fan of a popular Marvel superhero?

I can't imagine what was going thru the man's head and now his heart being ruthlessly spun in the midst of that sheetshow. You want peace? Let this man have some because he deserves it right now.
