dunno, a crest? a handkerchief? hawke wears a string around his neck that he got from fenris. i took shiny's hair and made a bracelet with stuff from places we went. i saw fenris wearing hawke's crest. i made my own crest out of a honeycomb, got the second one dipped in bronze ('cause the first one just broke) and shiny wears it on her belt. it could be anything to keep, so even when you're apart, they're there.
but we did that years before marriage, so it doesn't have to be because of marriage.
