Would it be possible to bring in a character with multiple Echoes already in place? For example, someone who came back as an animal and who wanders around in confusion for a while and may require several small "updates" before they are remotely interested in talking to people and/or ABLE to interact with people >.>

Second, what would happen if a Vermini tried to possess a small creature who happened to also be a reincarnated character? Or is that impossible to happen?
