After leaving the apartment (To wait for the analysis and so Java can take more pictures of Martin), The gang find another woman being attacked by the static monster. Martin tries to help, but it's too later. After the woman loses her face, Martin checks her ID, only to see that this new woman, named Valerie, looks just like Sophie.
