Just to help clarify for future IC posts: mutants and metahumans are the same in this world. Metahumans are the 'official' term for those born with the metagene (also known as the X-Gene). Mutant is the derogatory term originally coined when metahuman numbers began to increase. Modern metahumans have been trying to retake the term for themselves. 

This has been established through comments in the IC already, but just to avoid future confusion.
