Notes

• Hiro expresses his concern in a blog entry that he "might be risking a rift" by going back in time to save Charlie. In another Heroes Evolutions culmination, Hiro sends an email to Hana stating that going back to give Peter Petrelli a message is a rift, but that the "rift is not a risk. It can't be."
• In an interview for Heroes Unmasked, Masi Oka explains that Future Hiro gives the message to Peter as a way to communicate to his past self, presumably to avoid a rift.
