So now we know: Theresa May will go back to Brussels and plea for meaningful changes to the Northern Ireland backstop. If she can get concessions from the EU, then it looks like we have a deal.
But the EU has been utterly consistent in its position that the Withdrawal Agreement is not open for renegotiation. That means the backstop cannot be tweaked. So it's starting to look a lot like a showdown: May's deal versus no deal.
But didn't lawmakers just vote to rule out a no deal? They did. But it's not legally binding, and even if it were, it simply is not in the gift of Parliament to rip up an international treaty.
So May's deal, no deal, or something else? Goodness me. All eyes on Brussels; all eyes on opposition leader Jeremy Corbyn.
