After being recruited (and flirted) to the good side, Roger tells Marth how he really loves Caeda. Marth's response to this is pure silence.
And then we learn in Shadow Dragon's ending that his title is "Still Single".
Shadow Dragon's endings have some funny notes:
Rickard is stated to have returned home. Shortly then, though, it's mentioned that the area around his home was robbed continuously.
Minerva helped to make Macedon flourish. Everyone in there wanted her to be queen, but the only one who didn't want to be queen...was herself.
Everything Rickard says and in BS Fire Emblem Episode 3. Absolutely EVERYTHING, especially his dealings with a suspicious Nabarl. Seriously. Kazue Ikura's performance as him is absolutely spot on and thoroughly hilarious.
