Kelly was a marine? I only remember her wearing a uniform, and that her hubby got a face full of inner mouth, that's it, didn't even know she had a name. I also clicked on this forum to see who Kelly was. I don't know who was the stronger character, but Lex was more memorable, probably b/c she was the main protagonist. I think the only thing that would make Lex a stronger character was that she taken out of her element: she a cliff climber, not a combatant. But I don't remember a lot of Kelly except her running around with her daughter.
