It's not what they say on the stage but how voters from different countries behave.
UK: 0 points total
Cyprus: 12 points from Greece
Azerbaijan: 12 points from Turkey
San Marino singer: A Turkish guy sings in English
Armenia: the song is in English instead of Armenian
It gives you a clue on what's going on in every country. How nationalistic they feel this year, are they fixing their issues with their arch enemies, are they opening up to different cultures, do they feel part of the community, is everybody still annoyed by the Brits and did they took the event seriously enough to send a good song etc.
