TeenNick will air the next episode, Underneath it All, part 1 on Monday, Feb 20th at 9:00 PM ET. Underneath it All, part 2 will then air at the same time on the Friday after that on Feb 24th.
On that same day, the 24th, and at the same time, Much will air both parts of Underneath it All in an one-hour block.
After that little mess, both Much and TeenNick will then air the remaining episodes on Friday at 9:00 PM ET.
Hope that helps.
