Otto seemingly removes Peter’s consciousness by erasing his memories (Issue 9). Without the influence of Peter’s consciousness, Otto further blurs the definition of a hero (Issue 14). This part of the story really puts forth the idea that a person’s consciousness is not only influenced by but is made from that individual’s memories and experiences.
Although not in total control of the shared body, early in the series Peter’s consciousness has access to Otto’s memories (Issue 3). Otto controls which memories are brought to the forefront, but Peter explores them.
Memory involves three different stages: encoding, storage, and retrieval. When people pay attention to stimuli in their environment, what they pay attention to is encoded into a memory. That memory is stored first in the short-term memory (also called working memory), which lasts about 30 seconds, and then if that information is important, it goes into the long-term memory. Memories are retrieved when they are brought out of long-term memory and back into attention in the short-term memory.
Sometimes, memories are encoded, stored in the long-term memory, retrieved, and then are re-encoded with new information. Then next time those memories are retrieved, they are remembered with the newest information.
As mentioned, Otto removes Peter’s consciousness by erasing his personal memories. In order to do this, Otto, somehow, goes within himself to fight Peter’s consciousness with his own (Issue 9). For strength, Peter retrieves his positive memories, while Otto retrieves Peter’s memories of fear, anxieties, doubts, and failures in order to gain control and erase the memories.
