I hope it doesn't mean attack is immenent. I am playing as England right now, I own the British Isles, north France, and a few places in the Holy Land. However, a Byzantine Princess keeps doing that animation thing at Paris. And a Venetian Diplomat at Metz. Although I don't see why either of these teams would be planning to attack me (although the Venetians do have Bern...).
