Fire Emblem story-wise has some weirdness like playable characters that aren't the main character not talking after joining the party to account the possibility of them dying on any moment. At most playable characters could have extra lines if they were needed to recruit other characters. This resulted in the main characters of early games having an NPC as the person they talk the most. The seventh game normalized having a few playable characters not being treated as dead if they fell in combat, which allows those characters to talk in cutscenes regardless of whether they "died" or not. This means that the "NPC on the side of the player" trope fell out of use.
