As the Queen of Winter enters, Deadly deftly manages to turn around in place; he'd been about to join Magnus before Katrin arrived. He approaches the Russian woman with a bow and a flourish before pulling a white rose out of one of his innumerable pockets. Granted, it's made of plastic and designed to be turned into a magic wand and back, but it makes for a lovely gesture. He debates staying and chatting for a moment, but it's probably already caused enough of a stir by being the first to greet the Queen without being of her Court.
He understood politics: Too many films seen not to. He just hated them.
