Shen seems to almost have a split personality, and it's always unknown what he'll be like upon waking up. One moment, he'll be the happiest Tokota alive, play fighting, grooming and darting around with his packmates without a care in the word, and the next, he'll be sour, grumpy and bitter. Depending on what mood he's in, will depend which of his packmates he will hang around with, though it's noted he always spends more time with the males over the females. He's just being friendly. Right?
