^^ maybe he's come back to Brussels specially to meet her; it's easy to see why one would:
I previously supported Scottish independence, but this timing just won't work. The Scots need to wait and see how things pan out, actually, they don't have the option...
A much more valid argument at this time, if it can be mutually agreed (I mean between the two Irish countries) would be Irish reunion. If the North want to stay in Europe then now would be a good time to fully integrate with the South; of course, that'd have to wait until after Brexit was complete too, but preparations could certainly be made.
