Hey, it's Epilogue, not Ending

Also note that Ardam's was the only one to really imply the passage of a large amount of time. These epilouge sections may not be all 'ending' at the same point in time: heck, it's mentioned in Drecker's comic that he only spent 1 year travelling the world. Like Milo said, it's most likely that these segments are about personal things that happened before the couples pair up or while they're still getting settled (which is possible in Karn's case).
