On the first episode, if you choose to go to Prince Lawrence first and save him, the trailer for episode 2 has him crying. On episode 2, there is no Prince Lawrence present. What the hell?
Telltale had made some very drastic story changes between episode 1 and 2. The trailer at the end of each episode is just a general idea for the next episode and nothing is set in stone.
Pretty much this.
There's a thread dedicated to it if you want to dig it up.
They rewrited the whole story for some reason. That is actually the reason of episode 2 really late delay,
