Oooohhh, yeah, Ji kinda fascinates me! The fact that he managed to survive, alone out of all Xuan's brothers... and he's clearly aware of why, and hoping against hope that it'll keep working...

Nobody in the Xiao family reaches a ripe old age without becoming a mastermind. Xuan and Ji just took opposite routes: "I'm the acknowledged champion schemer" versus "I'm so good at it, nobody even knows I'm scheming." :D (Quick, where's that XKCD comic about viral marketing? That's totally Prince Ji.)
