♈: the most daring thing your muse has ever done
This is a tricky question, because “daring” is a subjective word.
Kai is a physically strong and unafraid person, and has done some fairly remarkable things with his strength (though he tends to be clumsy at times). During a training exercise he and his teammates had to get over an obstacle, and he heaved both of them over in a burst of adrenaline before leaping over it himself, rather than taking the safer, more circuitous route that would have lost them time. That move impressed his evaluators. However, Kai didn’t feel it was daring; it was just who he was, so it wouldn’t even register as that.
Kai is a cautious person in general, and thinks carefully about his decisions. His choice to travel with the Doctor as a regular companion was a daring one for him, because he is pushed far out of his comfort zone by that, and led to do more than he ever would have otherwise. This is probably what Kai would admit was the most daring thing he’d done.
Kai is a very privately emotional person, and talking clearly about his feelings with someone he loves is challenging for him, because of the intensity of what he’s feeling. Confessing his feelings would be an incredibly daring act, but would be one he wouldn’t open up about if pressed.
Kai doesn’t always realize that his physical courage is unusual. He’s acted more than once to save someone else’s life at the risk of his own, notably the Doctor but also other people he’s met on his journeys, and while he usually deals with emotional and physical fallout after the fact, he wouldn’t label them as daring, but just as “the right thing to do.”
He’s quite a complicated dude XD
