Ok, for starters I agree with QV on the argument topic.
And staying on topic, I agree that Kopa=Fluffy. (Who would name their child fluffy?) 0_o... Anyways, it makes complete sense, especially with the whole Zazu "Merderous outsiders." thing and Simba being WAY to over protective. I can see some points here too, like why would Nala be so calm about letting Kiara go off on her own? Well a cub has to have freedom. In the animal world animals, that includs cubs, get killed all the time! It's just a part of the Circle Of Life. I think the people who wrote TLK 2 were trying to stay somewhat close to real life animal behavior. I mean, even in the theatre on this site for TLK 2 production, they say that they closely study each animal they are using in the film. So ya there's my opinion. I think that Zira DID kill Kopa and that Kopa was the lion cub at the end of TLK 1 and I am pretty sure that Kope=Fluffy, Fluffy is just a nickname. ^_^
