Rakka will still be staying with/hiding with the Dians and generally helping them with things now that they're back together and everything is okay. But oh god, that new murder is going to freak her out, and only confirm in her mind that she needs to keep hiding out for a little longer.

Case being, she wont be going out to fight the monster car or meet Geoff the Alien, but she might call him if she can get the number. She will go out eventually to start her "angel training".
