Watch the episode Simon Says again. Listen carefully and closely to EVERYTHING Hawkmoth says and tell me that you realized that we could have found out his identity in Season 1 before The Collector was released.
You mean in stone heart part 1 right because hawkmoth is show holding a pic of Miss. Agrest in his locket
actually you have to LISTEN to what Hawkmoth says in the episode 'Simon Says'
What do you think?
