Ratings Are In 4/14/15: Family Guy down a dozen

It took more than a month, but Family Guy returned with a new episode on FOX this past Sunday Night, unfortunately, I don’t think anyone even knew about it according to a new note from Deadline.com:
Fox aired original of Family Guy (1.5, down -12% from its most recent original).
A new episode of The Simpsons airs this Sunday Night on FOX, so it’ll be interesting to see if FOX starts bulking up its marketing efforts sooner rather than later. Family Guy could sure use it.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
