Seriously. Nothing about it really stood out, except for finding out that Gerome lent Lucina his mask for her "Marth" masquerade. Hell, they didn't even resolve the subplot of looking for the artifact that Lucina lost in her B support or even reference it in their A support. Maybe the S support touches upon this, but I had already married Gerome to Morgan beforehand (through an accident involving multiple save files and forgotten details).
