First of all, I wasn't disturbed by the one panel of May. However, I think Slott is wrong in practically attacking readers through this long tweet. Especially considering how much hype he put behind it to make people think it was going to be disturbing. The dialogue used by May, telling Otto to not be a "fuddy duddy", implies that something risque was going to happen/happening. Where I am from, calling someone a fuddy duddy is equivalent to calling someone a wet blanket. Based on that, my interpretation was more than just Otto simply seeing the bride early; as Slott "intended".
