UPDATED 7/4/15: So it looks like TeenNick and MTV Canada will air 14B on the same schedule after all.
According to MTV’s July press release , MTV had no plans to air the first two episodes on July 20th, leaving MTV to air an overwhelming majority of 14B a day behind TeenNick. However, the broadcast schedule listed on MTV’s website has both 1413 and 1414 airing on the 20th.
I guess they couldn’t say goodbye without giving us one final network screwup! Here’s what the broadcast schedule looks like, courtesy of Degrassi Source:
