Actually, it's a webisode they are airing. I forget how many episodes like this...but they follow a Walker attack in the air. (i.e. someone on board is sick, and presumably dies quickly enough to start an attack on the plane.)
So not a commercial.
Not sure if it will come into play next season
Typically, the webisodes operate on a fringe connection to the series.
- In "The Pact," a man and woman are the only survivors of their overrun camp, only to end up at the same hospital were Rick was in a coma.
- In "Cold Storage," the hero just so happened to find the Grimes family storage unit in his search for clothing, but that's where the connection ends.
- "Torn Apart" featured a split family, but the only connection to TWD was the featured character turned out to be the "bicycle girl" / torso zombie Rick encountered in the pilot.
