1. In the first 15 minutes of the episode, the following things occur: A picnic, note-passing, purple smoke, mention of Pompeii, and two offers that Emma doesn’t really know how to refuse.
Now that we know the note passing is Hook giving Emma the note with Neal’s address, I think one of the offers that Emma doesn’t know how to refuse is the opportunity to go to Neal’s apartment. The other offer you’d think would be the proposal, and if she “doesn’t really know how to refuse,” I guess she says yes? But then she seems to still be at the table after Walsh leaves, so maybe not? Unless Walsh is just in the bathroom when Hook gatecrashes their date?
