The Hardy Boys Nancy Drew Mysteries/WMG

Frank is actually trying to kill his younger brother Joe

 * Look at the episode "The Creatures Who Came On Sunday". The ep's opening titles say we're in New Mexico...but not 2 minutes later, the Hardys are pulling into a burned-out gas station, and Frank pulls out a map to trace a route to the next town -- and he's looking at a map of Montana, and tracing the Missouri River to get to Great Falls. Obviously, Frank plans to dump his gullible geographically-challenged brother in the river in the back country. Muahahahaha.

"Joe: (gesturing Frank ahead) Well...you're the oldest.
 * Also check out "Voodoo Doll", where Frank shoves Joe out front into danger, as the brothers are about to open a creepy mausoleum as the villain watches.

Frank: Yeah, but you're more agile on your feet, and stronger.

Joe: Since when?

Frank: Since right now."


 * Sole Survivor, where Frank and his father Fenton think Joe has been killed in a car crash. Frank doesn't look all that broken up about the possibility...
