I think Hiro and Kenzei spent at least a few months working together. Still, it's a long time to hold a grudge. Then again, Hiro walked out on the girl afterwards, so I can imagine Kenzei would hold that against him as well.

One of the more confusing things I remember was Peter having a scar in the future. Yet, if Claire was alive, he should have had the healing power. So maybe whatever gave him that scar could be used as a last-minute plot device.
