Me too. Enzo can be way too aggressive at times towards Diego, to the point where Diego is too scared to even go and grab the food that Mike throws to him. There's multiple times where Enzo is bullying him by circling until diego has to defend himself. They both love each other, but sometimes those instincts kick in that say "hey I'm a tiger and there's another tiger in my territory". Since tigers usually have miles upon miles of territory to themselves.
