1. Watching his back
Micheál Martin's visceral relief at finally becoming Taoiseach will be an all too short pleasure. He will be just settling into the job when the swap deal with Varadkar takes place.
When stepping down from his current role, he must especially ensure he remains party leader - and thereby the Government's number two. That means keeping pretenders to his crown at bay. It might explain the snubbing of Dara Calleary.
2. Big Jim's gamble
Sometimes the wannabe king doth protest too much. Deputy Jim O'Callaghan is also brooding on what lies around the corner. But turning up his nose at the offer of a junior ministry could backfire.
He has now cast himself as public enemy number one for the new Taoiseach - and Martin will do his damnedest to cut him adrift. O'Callaghan risks becoming a sour soothsayer on the sidelines, making more enemies than friends in Fianna Fáil.
3. Sinn Féin looks jaded
It goes back to the old Mary Harney line: the worst day in government trumps the best day in opposition. Mary Lou McDonald knows the odds are on this coalition more or less going the full course.
That means she and her party face a long, grinding road ahead. Talking the talk - but never walking the walk. The party will get a second wind. But right now her frontline team look spun-out, thinking of all those sterile days ahead.
4. Using his elbows
There was a time the Labour Party could mix it with the best of them. Always on the cusp of power if the figures fell its way. But no more. Now the left-of-centre vote is spread all over the place. Labour's new leader, Alan Kelly, will fight like hell to punch above his weight on the Opposition benches. And that means not playing second fiddle to Sinn Féin, the Social Democrats or any arriviste socialists. They all nicked old-style Labour seats.
5.Fine Gael's second wind
One would hardly think it now, but Leo Varadkar and his gang had a fairly grim election. However, Covid changed everything. The leader and party have a renewed pep in their step given their recent surge in the polls. Varadkar not going first as Taoiseach might also land him an unexpected fair wind.
6. Cromwell and all that
All politics is local - or so we are told. The 'Cromwellian controversy' dubbed the lack of a full-blown minister west of the Shannon a disaster of historic proportions.
A Cabinet heavy hitter can direct goodies to his or her constituency. But the fortunes of a huge geographical swathe will depend on the ebb and flow of national politics.
7. Greens turning yellow
There could well be a few defections by party purists - and it could be hell for those remaining in Government. The main problem is that apart from climate change challenges, grim tidings abound. To use a Bob Dylan-inspired Met Office analogy, "A hard rain's gonna fall". Belt-tightening might be the order of the day. But if the Greens cut and run en masse, they may face a general election wipeout.
8. All those billions
We have no choice. But we are risking another roll of the dice with that entity known as our national debt. What Ireland Inc now owes strides towards the stratosphere. Interest rates are low, so things could be much worse. But the danger is we become like Italy - a country forever hogtied on an economic precipice.
9. You never know
On the other hand, things might surprisingly come together over the next few years. A coronavirus vaccine of some hue is not beyond human ken. And there may be a post-Covid kick in the US, EU and UK economies. There was a general upswing after the Second World War. A rising tide will lift many boats.
10. Martin's run in the sun
A quiver in Micheál Martin's voice while accepting the role of Taoiseach told a tale or two. His has been a long and fitful journey to the sunny uplands. Many will not begrudge him a run in the sun - at least for now.
