Spoiler about Ep 16
Yeah he would be in Heart of Darkness if that is about after Snow takes the potion. I would imagine that Snow would say where she is going and that maybe Charming will come to the dwarfs house and ask about her. It is sort of like Chainfire, but opposite. The sort of effect to Snow's character that she no longer knows Charming is that she still really wants to kill the queen.
