Check out the promo for next week’s episode of ‘Gotham’ titled, “Knock, Knock.”

What did you guys think about the Season 2 Premiere? How about that letter Bruce’s dad left for him in the cave?

“Dear Bruce, these last weeks I begin to feel very mortal, which prompts this note to you. Perhaps I’m being paranoid. I hope so. In any case, if you’re reading this, then I’m dead, and you figured out that the entry code is… BRUCE. I’m sorry I had to hide this part of my life from you, because this place only exists because of you. Becoming a father made me want to be a better man, and I started asking hard questions about the family business. So here we are. As I write this, you’re 12 and a fine, good-hearted boy. So I’m sure you’ll be a fine, good-hearted man. But that’s all I know. I don’t know what happened to me or your mother, or how life has turned out for you. I don’t even know how old you are. So I’ll resist giving you much fatherly advice. Only this: You can’t have both happiness and the truth. “You have to choose. I beg of you, my son, please choose happiness. Unless… Unless you feel a calling. A true calling.”
