Popped up Abroad begins & ends?

I'm a little confused by tonight's lineup it kicks off at 8:00 with the series premiere of Popped up Abroad on Nat Geo, or does it?

Chiller has an original telefilm Brian Keene's Ghoul up at 9:00 and also in that slot on CBS is the 2 hour special ACM Presents: Lionel Richie & Friends in Concert.  If neither of these sound like a good time then check out TLC for the 2nd premiere of Say Yes to the Dress: Bridesmaids.

At 11:00 on Nat Geo is the 1st season finale of Popped up Abroad...see my confusion here?  The series starts at 8 & then the finale is at 11...at least that's what my data says but when I pull up the guide Nat Geo is rerunning all of the Titanic stuff from last weekend that I wrote about & Popped up Abroad is on 4/20 with a marathon running from 8 to 12 which would explain the start & finish of a series in one night.  I guess tonight will be a crapshoot but I suppose that's what you get on a Friday the 13th, nothing is as it seems.
