Maleficent is likely to get an episode and some for her backstory.

So far it's, Premiere, Snowing/QoD, Mal/Reg, Ursula/Hook, Episode 16, Hood, Cruella, Lily/Emma, Reg?, Episode 21, Season Finale. So, Maleficent isn't going to get a big centric arc, since none of the major villains get more than two episodes for back story, unless it involves someone else and now there are three villain backstories to do, look how far away Cruella's is from the rest. So Autumn is likely not related to anything before 4x18, so unless Maleficent has another backstory she's likely not involved in it or maybe she's a part of the next season's plot.
