So whats wrong with Martha Meeks? Anyone related to Randy has to be awesome. I think if Randy were to return in Scream 4 it should be in a dream Sid has. In her dream she could be sitting on a bench in a cemetary or a park with no one around but then Randy walks up to her and sits down beside her. She tells him that its happening again and explains whats happened and that she doesn't know that she can handle this anymore she's at wits end, and he tells her that soon they'll be together again in the afterlife. If he tells her that instead of encouraging her or giving her some cliche "rules", it will make the dream more scary.
Kincaid - We're dealing with an ordinary, flesh and blood killer. And I know how to handle guys like that.
Sidney - Oh yeah, how?
Kincaid - Catch him... or kill him.
