Thor's smile falters a little when he realizes that everyone's attention is on him. It's not a position he hasn't been in countless times before, but he hadn't exactly expected it right now, and a vague look of I've made a mistake flashes in his eye as he struggles with how to respond. Does he make a joke and laugh it off? Should he just start singing? He'd look like a fool if he did it alone.

It's Rocket of all people who comes to his rescue. He's had enough experience with Terran birthday nonsense to know this tradition, too. "Not until we set the cake on fire, it ain't," he says, immediately abandoning his plate of food next to Nebula to get candles and a lighter.

"Yes, exactly," Thor agrees quickly, rallying himself in the reprieve that moment gives him.
