Of course, Halseys efforts werent always positive.

to create the Spartan program, she kidnapped children, tearing them away from their families.

As befits such morally gray characters, Halsey and Cortana have a conflicted relationship.

Halsey herself recognizes this strange relationship in her journal, asking, Am I playing God…or mother?

Even those seven years were a stretch.

But that isnt the technique she used to create Cortana.

Cortanas effort to take over humanity is, she thinks, for humanitys own benefit.

Halsey thought the same about the Spartans.

Its difficult choices like these that characterize Halseys careerand tend to wound the people around her.

Cortana has another sister, too.

Halsey writes about Miranda often, and seems concerned, but justifies her distance.

Miranda does not have a strong relationship with Cortana, even though they worked together briefly at Delta Halo.

It is unknown whether Miranda knows that Cortana was directly copied from Halsey.

Halseys views about her own actions change depending on the author writing her or the period of her life.

When Halsey and Cortana meet again, I hope that their fight is given the gravitas that it deserves.
