I really hope that he returns in a big and unexpected way, I was sort of thinking about Halo 2 and the thing that I loved about it, was seeing his side of the story coincide with the chief’s. I didn’t know this at first, but what surprised me was the hate coming from the fans. A lot of them disliked playing as him and this was the reason Bungie cut out his missions in halo 3 which really disappointing me. Halo 3 could have been a lot more interesting seeing his struggles and the game could have been longer with more depth. I highly doubt that he’ll be playable in Halo 4 since it is MC’s story, but hopefully we can see his return in Halo 5.
