Britt Robertson, who played Angie, has said that it is unlikely that Junior killed her character in the show. She also ruled out the possibility of Melanie killing Angie.
When Entertainment Weekly asked Britt who killed her character, the actress said, "I don't know. I know it's not Junior. There's no way he killed me unless the alien was controlling him. I don't think it was Melanie. She was the last person you saw but how could it be her? I think it has to be something someone we don't expect and just don't know."
