Okay I discussed this on a previous post but I want to really get into it. There is a minor spoiler for this but the book has been out for years so I can’t say I feel bad. But as many of us know 343 Guilty Spark is still alive and looking for a Lifeshaper. But my theory is, what if Guilty Spark was able to bring his friends back to and realized that he needed to help the humans beat Cortana. Since 343/Chakas regained a lot of his human memories maybe now he feels guilty for betraying Chief and his species. So to repent, kind of like Mendicant Bias did, Guilty Spark puts himself into an A.I chip and becomes Chiefs new companion in Halo Infinite? Obviously it would be hard trusting him considering he killed Johnson but if he can help defeat Cortana then I think it’s worth it.
What do you guys think?
I don’t think it would be wise for Chief to have someone like him in his head since their goals don’t align with each others’ yet again. Last we heard about Spark, he set out to look for the Librarian. Chief and the rest of the good guys want to take down Cortana. One could argue that the Librarian would be an asset to Chief’s mission, but the point is that Spark’s focus would not be on Cortana which would be a detriment to Chief since that distraction would constantly be in his head.
