Isaac has changed names but I'll refer him as Isaac still. He walks up to where Jimi hides and Jimi hisses. I've never seen agression from him. It's super good he has some, because he only showed flight. Agression is a a start of healthy bravery. I love my lil Jimi so much. I just look at him and feel love. So I hope things will continue to go forward as it did. I don't care if it takes time. And of course I will love Isaac with time as well. He's so cute.
