There was that twitch again, it was definitely anger this time. What right did this asshole have to be so uppity? Caught in the middle of eating someone's heart like that was just a normal thing. That wasn't an unusual thing to see for Sanzo at this point but still. Creep.

"You didn't even bother to hide, I'd say you need some sense. I'm not here to offer you advice. You can get that from the next person to find you shoving a heart down your throat." Sanzo was being reasonable, clearly. Again he didn't bother to direct smoke away from Cassian, he might get some amusement out of seeing the asshole choke on it.
