Sai is a very cold wolf, expressing little feeling and great control over his emotions. Even his anger is restrained to a great level. The only emotions he shows regularly is irony and sarcasm. His motives are unknown which makes him a dangerous and unpredictable canid. He's shown to be cruel and heartless towards others, and, though he joined the Clan, nobody truly knows where his allegiance lie.
Exclamation Point (ep 10)
Sai appeared in the scene where Silkey and her soldiers prepare to battle One-eye. He is shown to be impatient and doesn't like waiting so long with the preparations. He later showed up in the final scene at One-eye's den with the rest of the patrol.
