Will the mold make a return yet again? If so, perhaps it can be used to help strengthen a preexisting virus to make something like the Cameron Virus. I personally would like for them to canonize 4D Executor or reimagine it to make it more relevant. Since Miranda was a shapeshifter and the C-Virus literally made an Ada clone, I can see them doubling down on this concept. RE8 already combined mold with Cadou so a virus either enhanced or created from the mold would be interesting to join both old and new.
