Factual error: Aphrodite's son and Psyche's husband is Eros, not Cupid. Venus's son is Cupid. (Eros is Greek and Cupid is Roman).
Factual error: When the missile intersects with the asteroid, and nothing happens right away, Arturo mentions to Bennish that light travels at over 186,000 miles per second, implying that the light from the explosion will take a moment to become visible. The problem is that by the time the missile is about to hit the asteroid, the light from the missile itself will have just as much lag time as the asteroid's explosion. The explosion should therefore have appeared immediately upon seeing the missile hit the asteroid.
Factual error: The episode has Mona Lisa and Teddy traveling to Yakima, Washington, showing green, tree covered hills. Yakima is in the middle of the Washington State desert, so the topography would be mostly flat, desert terrain, with yellow and brown colors.
Suggested correction: Don't think you have ever been to Yakima because Yakima is surrounded by hills and the only part that is flat is in the valley and Terrace Heights. I live in Yakima, and the map they showed of E Yakima Ave and Chestnut Ave and filming is wrong, though, because that area of the map is mostly neighborhoods, small businesses, and mini-marts. No trailer parks with a bridge nearby that has hills behind it in that area.
