Hi,
I dont know if I'm the only one thinking this but I think that because master chief is lonesome in the desert, that on his journey to help cortana, he should come across a dog or alien dog which comes along in his travels and helps him out along the way. Due to him not having any company he should have someone or in this case something. And whilst I'm on this I am deeply upset that halo 5 isn't on Xbox 360 :'(
