The stage is set for the final scene in the drama over speaking time that has swept aside the customary niceties which help to get the political work done in Leinster House.
Expect chaos, bitter words and little sign of resolution.
A crippling trade war is in the offing and the housing crisis shows no signs of easing, but the Dáil cannot yet properly grapple with these big-ticket items.
It needs one more shot at procedural catharsis before that pressing work can begin in earnest.
At the root of this seemingly intractable dispute are the Government-supporting Regional Independent TDs, which are effectively led by Michael Lowry.
Their support has seen a bespoke speaking slot created for them.
They are to be called 'Other Members' and will share this new time on the Dáil schedule each Wednesday and Thursday with coalition backbenchers.
To the Opposition it is a ruse that in real terms casts this group onto their territory, which is the speaking time reserved to hold a government to account.
The Government insists it is about respecting each TD's mandate and ensuring that Independent TDs will not be scared of joining future administrations.
The Ceann Comhairle has already ruled that the four Regional TDs supporting the Government cannot be classed as members of the Opposition.
But now Michael Lowry, Danny Healy-Rae, Barry Heneghan and Gillian Toole will get to put their questions to the Taoiseach and Tánaiste in a manner that looks a lot like Leaders' Questions. That is the key part of the Dáil day when the Opposition quiz the government leaders.

The Government has the majority to get this through but the route to the Dáil vote is perhaps less straightforward.
From the moment the Dáil resumes today this matter will be raised and there are likely to be interruptions aplenty on the way to the planned 3.10pm vote.
That could see the Dáil adjourned as disorder takes hold.
Such an unruly scene will take place against the backdrop of sombre discussions in Government Buildings last night about tariffs.
Worried ministers drew up plans around how best to work with the US companies based here and how to contribute most effectively to the EU response.
That widespread trepidation about this country's economic future will soon trump the Dáil row.
Already some in the Opposition are privately beginning to murmur that they do not have an appetite for a long war on this issue.
But that is for another day, the next hours will be all about disruption.
