It's probably the wrong time for it, but Chris has always been shit at picking the right moments for this sort of stuff. Because Cissie kisses him and he's wanted to do just that for a while now. Only, he never thought it'd happen standing over his grave. It's fucked, and he knows it, but just then, he doesn't think he cares. Chris kisses her back, though he maybe holds it a bit longer than Cissie originally intended.
