Begfhn wrote: Mother definitely takes place between The Heart is a Lonely Hunter and Lacey Well, yes. That's the general consensus. But when we don't have any other episodes to connect it to... It's obvious this episode is concurrent with Wonderland's To Catch A Thief, since Will and Alice steal Percy from Cora in said episode, meaning she'd just gotten back from Misthaven.

I would even go so far as to say Mother is before True North, which is concurrent with 7:15am. But that makes no sense, since by 7:15am Snow and Charming have already met, meaning Marian is already dead, yet by Nottingham's dialogue in this episode, she's ill, meaning she's probably early on in her pregnancy.
