Okay so I'm really new here and I figured that I'd give this a shot...
I love Cortana and I was sad that she died but I think it would be interesting if Master Chief got a child/pre teen like AI (Has humor and lightness but can be serious in certain situations). I've been thinking this because I just started reading the books (Halo: The Fall Of Reach) and I noticed that Chief doesn't really know how to react to certain things...so I'm just curious on how Chief would react to a child like AI. Just an opinion no flames please lol.
