honestly while we "meme" about ceroba being retarded, and her versus toriels kid killing count, but I think they do work as a good contrast in character between eachother. Toriels avoidant approach to her issues, ceroba making her own issues worse with the one track mind way she handled things. things got a little (a lot) messy in the story with the original version of ceroba clashing with what she became but overall it feels like they made something that highlights some characters from the original game really well. Martlet on the other hand is fleshed out really well when you take every route together, and personally comes out as my favorite character at the end of all things, but when you just look at the pacifist route it just feels like they tried throwing "discount papyrus" at the wall.
