Although Rosenthal had been eliminated by Harris during the penultimate Rose Ceremony, that didn't prevent him from returning during the finale to profess his love for her. She rejected him for a second time.
Similar to Rosenthal, Pavelka reappeared on The Bachelorette after being rejected by Harris -- however it wasn't to try and win her back.
Instead, Pavelka warned Harris about fellow suitor Wes Hayden, claiming he had a girlfriend back home. Hayden subsequently denied the accusations when confronted by Harris and Pavelka and reiterated his denial following his ouster.
ABC announced in May that The Bachelor's fourteenth season will premiere in midseason -- presumably early January -- and air in the Mondays at 8PM ET/PT timeslot Dancing with the Stars' ninth-season performance episodes will occupy this fall.
