“Visitors of the fifth kind”? Huh. I’ve heard of the third kind, and I think the fourth kind... Is there a fifth kind? I guess I could look it up, but I’m just going to assume alien encounters of the fifth kind involve door-to-door sales aliens.
Tedd’s logic is a bit flawed. He could just warn his dad, and given the layout of the house, anyone there would have to actually enter the house to see anything given the door and wall placements.
Of course, who thinks straight 100% of the time. Carry Grace to the basement plan, GO!
