I keep forgetting that Granny’s was in the enchanted forest, so it looks like Lancelot and Snow head there to hide the dagger or to meet in secret about hiding the dagger. I am starting to think when Snow says you followed us she is speaking to BOTH Charming and Arthur. Charming probably knows how to track his wife and this could definitely lead to some drama for snowing. Perhaps that is in part how they failed Emma.
Also I don’t think the Gauntlet will be too big of a plot point. I am guessing they run into or seek out Rumpelstiltskin and they make a deal for whatever is in that bottle Rumple is holding?
