Yeah cinni .. someone that hasn't seen the HII yet might say it or since its used someone at TC says it.
Could be Cassandra though? like when Dre tells them that Mookie has the HII Cassandra might ask what it looks like and might excalim "its a turtle!?? or Earl & Yau-man might play stupid and say it? OR someone finds the fake idol and when he shows it to someone they tell them thats not it and that its a turtle
Maybe Jeff's preview will have the answer?
