How Yellow Will The Greens Become?

So the Greens seem to have agreed to go into a coalition with the SNP on the basis of no new nuclear power stations and a massive reduction in carbon emissions. As the SNP were already signed up to that what's the deal? I wonder if little cousin Robin mentioned the M74 expansion and the policy on more direct flights to Scotland that the SNP are in favour of? Maybe he's not even half way up the stairs.

Halfway down the stairs
is a stair
where I sit.
there isn't any
other stair
quite like
it.
I’m not at the bottom,
I’m not at the top;
so this is the stair
where
I always
stop.
