Five episodes into season four and Emme hasn't appeared once. The last time I can think of this is Judy Winslow in her final season of Family Matters (also s4) before her character disappeared, except that season had 24 eps. MWAP will likely only have 13. It seems like she had a scene in the premiere that they cut: https://www.instagram.com/p/B-c5HEBBZTP/

She finally appeared last night!
